# The project manager's primary responsibility during team conflict is to engage directly with the team to facilitate resolution and restore team performance. This includes using interpersonal and leadership skills such as active listening, emotional intelligence, and coaching. When there's confusion about change requirements, the project manager should first clarify with the team before escalating or deferring. The PMBOK Guide - Seventh Edition emphasizes that project managers should foster open communication, resolve conflict early, and clarify ambiguity through engagement. Option A undermines collaboration and may create resentment. Option C (HR) is inappropriate for technical disagreements. Option D escalates too early before using team-level conflict resolution.
