Explanation
The BA should obtain approval from the project manager before selecting the participants for the requirements elicitation meeting. This is because the project manager is responsible for managing the project resources, schedule, and budget, and ensuring that the project objectives are met. The project manager can help the BA to identify the appropriate stakeholders who can provide valuable input and feedback on the requirements, as well as to avoid any conflicts, duplication, or gaps in the elicitation process. The sponsor, the end user, and the subject matter expert are potential participants for the requirements elicitation meeting, but they are not the ones who can approve the selection of the participants.
