Explanation
A functional requirements specification (FRS) is a document that defines what features and functions a system should provide to meet the business needs and objectives. It describes how users will interact with the system and what outcomes they expect from it. An FRS typically includes use cases, user stories, acceptance criteria, data models, business rules, workflows, diagrams, mockups, and other details that describe how the system should work. A BA should create an FRS to define the enhancement features for the current Salesforce CPQ implementation that must be configured in the next phase of the project. References:

Explanation
The user story that the business analyst should write to describe the functional requirement is:
As a sales clerk, I want to see item availability and locations to help customers find items.
This user story follows the standard format of "As a <role>, I want <goal> so that <reason>". The role is
"sales clerk", the goal is "to see item availability and locations", and the reason is "to help customers find items". This user story is concise, focused, and valuable to the user and the customer. It does not specify how the goal will be achieved or implemented, which will be defined later in the acceptance criteria or design phase. References:

Explanation
The type of process diagram that the business analyst should use at the beginning of a Salesforce project to outline high-level process areas such as "Prospect to Contract" is a capability model. A capability model is a visual representation of the core capabilities or functions that an organization performs or delivers to achieve its strategic objectives. A capability model helps to identify and organize high-level process areas that span across different departments or teams, as well as highlight any gaps or overlaps in functionality. A capability model can also help to prioritize and scope Salesforce projects based on business value and impact.

Explanation
The business analyst should conduct elicitation with stakeholders regarding their parts of the process to close the gaps or confirm the process steps. Elicitation is a technique that involves collecting information and feedback from stakeholders or users about their needs, expectations, preferences, pain points, goals, etc.
Elicitation helps to close the gaps or confirm the process steps by allowing the business analyst to ask questions, clarify doubts, verify assumptions, resolve conflicts, or validate information with the stakeholders who are involved or affected by the process. Elicitation also helps to ensure alignment and engagement among the stakeholders on the process definition and design. References:

Explanation
The document that the BA should use is a journey map. A journey map is a visual representation of a user's experience with a product or service over time. It shows the user's actions, thoughts, feelings, pain points, and touchpoints at each stage of their journey. A journey map helps to understand the user's needs, expectations, challenges, and opportunities from their perspective, and identify areas for improvement or innovation in the product or service. In this case, the BA wants to improve the UX of marketing employees who manage webinar data. A journey map can help the BA to understand how marketing employees interact with Salesforce Campaigns at each stage of their webinar management process, what are their pain points and frustrations with the existing functionality, and what are their desired outcomes and goals.
