Explanation
Frequent product releases are beneficial for several reasons. They enable teams to inspect and adapt more frequently, which means they can get faster feedback, validate their assumptions, and improve their product incrementally. They help teams better understand and meet customer needs, which means they can deliver more value, increase customer satisfaction, and build trust and loyalty. They help teams to learn how to correct and eliminate errors, which means they can reduce waste, improve quality, and prevent technical debt. Smaller, more frequent releases are less risky, which means they can reduce uncertainty, avoid big-bang failures, and enable faster recovery123.

A Product Goal is a summary statement of the desired outcome or value that the product should deliver. It communicates the target future state of the product, which is aligned with the product vision and strategy. It enhances focus by providing a clear direction and purpose for the Scrum Team and the stakeholders. It is a commitment contained in the Product Backlog, which means that it is transparent, visible, and understood by everyone involved in the product development. It provides a long-term objective for the Scrum Team to plan against, which helps them to prioritize and refine the Product Backlog items and to craft the Sprint Goals.
Option D is not correct because the Product Goal does not need to have the approval of all stakeholders. The Product Owner is accountable for the value of the product and the Product Backlog, and therefore has the authority to define and communicate the Product Goal. The Product Owner may collaborate with the stakeholders to discover and validate their needs and expectations, but does not need to seek their consensus or permission for the Product Goal.
Option F is not correct because the Product Goal is not a contract with the business, but rather a flexible and adaptable guide for the product development. The Product Goal is not fixed and immutable, but rather emergent and dynamic. It can be changed or updated as the product evolves and the market conditions change.
The Product Goal does not limit or constrain the changes that may occur during the product development, but rather enables and supports them. References:

Explanation
* Option B is the best answer because it reflects the agile and empirical nature of Scrum and Product Ownership. The Product Backlog is a living artifact that represents the current understanding of what the product needs to be most valuable for the customers and the stakeholders1. The Product Backlog is not a fixed or static document, but rather an emergent and dynamic one that adapts to the changing environment, needs, and feedback. The Product Owner is accountable for managing the Product Backlog and ensuring that it is transparent, ordered, and refined2. The Product Owner collaborates with the Scrum Team and the stakeholders to inspect and adapt the Product Backlog items based on the new insights, opportunities, and learnings that arise from the changing environment34. The Product Owner also uses various techniques, such as product vision, value proposition, user stories, experiments, and evidence-based management, to define, validate, and prioritize the Product Backlog items5 .
* Option A is not the best answer because it contradicts the agile and empirical nature of Scrum and Product Ownership. The Product Backlog is not a requirements specification document, but rather a list of hypotheses and assumptions that need to be tested and validated in the real world5. The Product Backlog items are not detailed or fixed upfront, but rather refined and clarified as they get closer to implementation2. Updating the requirements specification document to ensure stability implies a plan-driven and predictive approach that does not embrace change and feedback, and that does not optimize value delivery.
* Option C is not the best answer because it contradicts the agile and empirical nature of Scrum and Product Ownership. The Product Backlog is not a project plan, but rather a product roadmap that guides the development of the product. The Product Backlog does not have a predefined end date or scope, but rather evolves and changes as the product grows and matures1. Keeping the Product Backlog the same until the end of the project implies a plan-driven and predictive approach that does not embrace change and feedback, and that does not optimize value delivery.
* Option D is not the best answer because it contradicts the agile and empirical nature of Scrum and Product Ownership. The Product Backlog is not a disposable artifact, but rather a cumulative and iterative one that builds on the previous work and learnings1. The Product Backlog items are not discarded or replaced, but rather refined and updated as the product evolves and changes2. Archiving the Product Backlog and creating a new one implies a disruptive and wasteful approach that does not leverage the existing knowledge andfeedback, and that does not optimize value delivery.
