During a daily standup in a hybrid project, two senior developers begin arguing about the architectural approach for a critical module. The argument escalates, consuming the entire 15-minute timebox and preventing other team members from providing updates. The team is visibly frustrated. What should the project manager do FIRST?

Allow the debate to continue until a resolution is reached to ensure the architectural decision is sound.

Intervene to end the argument and schedule a separate technical meeting with the two developers immediately after the standup.

Report the developers to their functional manager for disrupting the team process.

Make a decision on the architectural approach yourself to unblock the team.
