According to the PMBOK® Guide (Project Management Body of Knowledge), specifically within the Project Integration Management knowledge area and the Perform Integrated Change Control process:

Project Management Plan Updates (Option C): This is a primary output of this process. When a change request is approved through the formal change control board (CCB), any affected subsidiary plans (such as the Scope, Schedule, or Cost management plans) or baselines (Scope, Schedule, or Cost baselines) must be updated to reflect the authorized change. Other key outputs of this process include Approved Change Requests, the Change Log, and Project Documents Updates.

Work Performance Reports (Option A): These are an input to the Perform Integrated Change Control process. They provide the data (such as resource availability, schedule, and cost data) necessary for the CCB or project manager to make an informed decision regarding a change request.

Accepted Deliverables (Option B): This is the primary output of the Validate Scope process. It occurs when the customer or sponsor formally signs off on completed project deliverables. It is not an output of the change control process.

Organizational Process Assets (Option D): While updates to Organizational Process Assets (such as the change control procedures or historical databases) can be an output, the assets themselves are typically listed as inputs. In the specific context of this PMI exam question, " Project Management Plan Updates " is the more definitive and standard output associated with the administrative closing of a change cycle.

In the PMI framework, Perform Integrated Change Control is the process of reviewing all change requests; approving changes and managing changes to deliverables, organizational process assets, project documents, and the project management plan; and communicating the decisions. It ensures that only documented and approved changes are implemented, maintaining the integrity of the project baselines.
