In the MCC, comments are necessary when the status is which?

• A. When the status is NA
• B. When the status is UK
• C. When the status is NA or UK
• D. When the status is Rejected

Answer: (C)

In MCC, you provide comments when a status signals that something isn’t applicable or isn’t known yet, so the reason behind that state is clear to anyone reviewing later. NA and UK specifically refer to Not Applicable (or Not Available) and Unknown (or Undetermined), and both require a justification to explain why there’s no further analysis or data. This helps maintain a transparent audit trail and prevents ambiguity about why a item isn’t being acted on or how information is still pending. For Not Applicable, you’d note why the item doesn’t apply in this context; for Unknown, you’d describe what is missing and what steps will be taken to obtain it. That’s why the best answer covers both NA and UK.
