Answer:
A. Smoothing
Step-by-step explanation:
The smoothing approach is a conflict resolution technique that occurs when the project manager seeks to resolve the conflict by seeking an agreement that is beneficial to everyone, that is, seeking to reach consensus on a certain situation to mitigate divergences and thus focus back to work and not conflict.
This technique is a quick solution for the resolution of conflicts that is generally effective in the short term, because the conflict, even if it exists, is left aside while there is a viable solution, such as what happened in the question, that despite the two managers want the team member working for him full time, each of the managers gave in to have the employee working part time for each one.
