A team member is openly criticized by others during a standup meeting for failing to complete yesterday's tasks. What should the agile coach do first to address the situation?

Avoiding the discussion is too passive and allows negative behavior to continue, failing to protect the team environment effectively.

Letting the discussion continue goes against the purpose of a standup and can severely damage team morale and trust.

Waiting until the next sprint retrospective is too late to address an immediate and public breach of team conduct, allowing the negative impact to fester and potentially recur.

Openly criticizing a team member in a standup meeting is counterproductive and undermines team psychological safety, which violates core agile principles and the purpose of a daily standup. An agile coach's first action is to reinforce the agreed-upon team ground rules for respectful communication, effectively stopping the inappropriate behavior, and then immediately pivot the meeting back to its intended focus of discussing daily progress, planned activities, and impediments to maintain productivity and morale.
