By encouraging the SMEs to meet and come to an agreement together, the project manager is using the Collaborate/Problem-Solve conflict resolution technique. This technique involves working together to find a win-win solution that satisfies all parties.
According to the PMBOK Guide - Seventh Edition, collaboration is the preferred conflict resolution method because it leads to consensus and long-term solutions.
Option A (Compromise) is a lose-lose approach.
Option C (Synergy) is not an official PMI conflict resolution method.
Option D (Force) is a win-lose approach and not used here.

Effective delegation is crucial for project management, especially when managing a global team across different time zones. The project manager should delegate certain authorities to team members while ensuring that they have all the necessary information to make informed decisions. This approach promotes trust, encourages accountability, and leverages the diverse expertise of the team members. It aligns with the principles of good leadership and project management practices, which emphasize the importance of communication, trust, and empowerment of team members123. References:

A project manager should mentor the team member who is asking for directions and actions on many tasks, as this indicates a lack of confidence, competence, or clarity in the team member's role and responsibilities.
Mentoring is the process of providing personal support and guidance to a less experienced team member by a seasoned project manager. A mentor can help the team member develop their skills, knowledge, and abilities, as well as provide feedback, advice, and encouragement. A mentor can also help the team member understand the project objectives, scope, deliverables, processes, and standards, and how to align their work with them.
By mentoring the team member on a regular basis, the project manager can help the team member improve their performance, productivity, and quality of work, as well as increase their motivation, engagement, and satisfaction.
