When conflict arises due to communication preferences, the project manager should first seek to understand each individual's needs and preferences. Initiating individual conversations allows the project manager to assess the context behind each perspective and then mediate a resolution that supports team cohesion and project communication needs. Option A promotes team-building but does not directly resolve the specific issue. Option B risks inconsistent communication and confusion. Option D is prescriptive and may lead to resistance rather than resolution.
