Administrative closure of a project includes which of the following activities?

Closing all contracts is part of procurement closure, which is a specialized process related to, but distinct from, administrative project closure.

Creating performance reports is an ongoing process throughout project execution and monitoring, not exclusive to the final administrative closure phase.

Releasing project team members is a key administrative closure activity, formally disengaging them from the project and allowing them to be assigned to new work. This ensures proper resource management as the project concludes.

Obtaining a formal sign-off is typically done by the customer or key stakeholders, not from the internal project team members themselves.
