You are managing an agile project with a high level of requirements uncertainty. What is the best way to manage changes throughout the project to ensure the project goals are met?

Ask the development team to create a change management plan before the work begins.

Delegate authority to the team and the product owner to manage changes as they arise.

"Prepare a comprehensive change management plan, and manage to the plan."

Ask the product owner to refer all substantive changes to the change management team.
