In a hybrid project delivery approach, the business case is the artifact that ensures project benefits have been identified. It provides the rationale for the project by outlining the expected business benefits and aligning them with the organization's strategic goals. The business case is developed during the project initiation phase and is used to justify the investment in the project. It includes an analysis of the costs, benefits, risks, and opportunities associated with the project.
PMBOK Guide and PMP certification materials which discuss the importance of the business case in project management, particularly in hybrid and other project delivery approaches. The business case is a critical document that supports decision-making processes and ensures that the project aligns with the organization's strategic objectives and delivers the intended benefits.

The alignment between the project team and stakeholders is crucial for the success of a project. This alignment must be maintained throughout the project's life cycle, ensuring clarity of scope, risk, schedule, and price at each phase1. In a hybrid project management approach, risks should be reviewed during each iteration and review to ensure alignment between the project team and stakeholders2. This allows for timely identification and mitigation of risks, ensuring that all parties are aware of potential risks and their outcomes2. Regular reviews also facilitate open communication and collaboration, which are key to successful risk management3.

The PMBOK Guide emphasizes the importance of developing the project team. This includes improving competencies, team interaction, and the overall team environment to enhance project performance. In this case, the project manager should ensure that coaching meetings are in place for the new team member within the project timeline. This will help the new team member gain the necessary skills and knowledge to contribute effectively to the project.

According to the PMI-PBA Exam Practice Test and Study Guide, 2nd edition, chapter 8, page 179, incremental budgeting is a technique that allows agile teams to estimate and allocate funds for each iteration or release of a product. This technique enables the teams to respond to changing requirements and priorities, and to deliver value to the customer faster. Incremental budgeting also reduces the risk of over- or under- budgeting, as the teams can adjust their estimates based on the actual costs and benefits of each increment.
The other options are not suitable for agile teams, as they do not support the agile principles of flexibility, collaboration, and customer satisfaction. Requesting the finance team to allocate a budget based on historical data may not reflect the current or future needs of the product. Providing the budget to the finance team for only the planned increments may not account for the changes that may occur during the product development.
Extrapolating the budget based on the current cost performance index (CPI) may not be accurate or reliable, as the CPI may vary depending on the scope, schedule, and quality of each increment. References:

According to the PMBOK Guide, an iterative-based strategy is a release strategy that delivers the product incrementally over multiple iterations, each adding more functionality and value. This strategy allows the project team to obtain early feedback from the customers and stakeholders, and to adapt to changing requirements and priorities. In this scenario, the project manager should recommend an iterative-based strategy to maximize value by releasing the product to each country as it is finalized and ready for release in that country. This will help to meet the specific requirements of each country, and to deliver value faster and more frequently. References: PMBOK Guide, 6th edition, page 19-20. PMP Questions page 515, question
