During a retrospective, two team members engage in a heated argument about the root cause of a recurring technical issue. The argument is becoming personal and other team members are becoming uncomfortable. What should the project manager do FIRST to manage this conflict?

Immediately end the retrospective and schedule individual meetings with both team members

Intervene to refocus the discussion on the technical issue rather than personal positions

Ask the Scrum Master to handle the conflict since it's occurring during a Scrum ceremony

Let the team members work through the conflict themselves to build team resilience
