A team member is consistently late to the daily standup. The team has established ground rules that include 'Be on time'. The team looks to the project manager for action. What is the BEST response?

Publicly reprimand the team member during the next standup to enforce the rules.

Ignore the lateness as long as the work is getting done.

Ask the team during the retrospective how they would like to handle violations of their ground rules.

Impose a fine system for late arrivals.
