A team member is not happy to be assigned to a certain project manager's project. The team member has been communicating displeasure to the rest of the project team. Which of the following is the BEST

Providing general interpersonal communication training for all team members is a proactive measure but does not directly address the specific and immediate issue of one team member's discontent affecting the project's integrity.

Escalating the issue to the team member's functional manager might resolve the immediate problem, but it sidesteps the project manager's responsibility to manage their own team relationships and could damage trust with the team member.

Reassigning the team member to a happier task might temporarily alleviate their dissatisfaction but does not address the underlying issue of their displeasure with the project manager or the project, and might not be feasible or fair to other team members.

Sitting down privately with the team member allows the project manager to understand the root cause of the displeasure, address concerns directly, and work collaboratively towards a resolution. This direct, one-on-one communication is crucial for resolving interpersonal conflicts, maintaining team morale, and preventing negativity from spreading and compromising project integrity.
