During a critical project meeting, you notice that one of the key stakeholders, who usually holds an assertive and decisive personality, appears unusually reticent and disengaged. Based on the analysis of personality indicators, what should be your next step to address this change?
Assign someone else to take over their responsibilities assuming they are no longer interested.
Continue the meeting as usual and discuss the issue later in a team email.
Privately discuss any concerns with the stakeholder to understand their current state better.
Immediately ask the stakeholder to explain their behavior in front of everyone to clarify their position.
