Explanation:
Option A: If a new work is assigned or an additional work is assigned, it is necessary to first explain about the new responsibility and clarify about the assignment. This would ensure Kerry to continue the work smoothly.
Option B: Feedback is always welcome but this is not the first step to add responsibilities.
Option C: Notifying others is the responsibility of John and not Kerry. So this choice is invalid.
Option D: Accountability though it is mandatory comes only in the closure part.
