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.
