Explanation
For the address verification feature in the Northwind Electric Cars background check system, two behaviors are needed: (C) The 'Verify Address' command bar button should only be enabled when the address has not yet been verified - this prevents unnecessary duplicate verifications and makes the UI intuitive by signaling when action is needed. (D) If any address field is modified after verification, the 'address verified' flag must be automatically cleared - this ensures data integrity by forcing re-verification whenever the address data changes. Making fields read-only after verification (A) would prevent legitimate corrections. A confirmation dialog (B) adds friction but does not enforce the correct business logic. Both C and D together implement the correct guard conditions for the verification workflow.
