After issuing a duplicate, if the original certificate is found, it should be canceled by the proper officer.

• A. Canceled
• B. Reissued
• C. Archived
• D. Invalidated

Answer: (A)

When handling duplicates, the aim is to keep only one valid certificate in circulation. If the original certificate is found after a duplicate has been issued, it should be canceled by the proper officer. Canceling the original formally revokes its validity, preventing two active certificates and maintaining a clear, auditable record. Reissuing would create another active document, archiving would not revoke the original, and while invalidating is similar, the standard administrative action in this scenario is cancellation.
