A virtual team is struggling with low engagement during conference calls. Team members often multitask and silence is common when questions are asked. What is the MOST effective way to improve engagement?

Mandate that all team members keep their cameras on at all times.

Increase the frequency of meetings to ensure everyone is paying attention.

Implement random spot-checks by calling on specific people to answer questions.

Restructure meetings to be interactive, using polls, breakout rooms, and collaborative tools.
