DreamHouse Realty has a policy that requires the phone number on Contact to be deleted...

The correct answer is D. Flow.

The requirement is to automatically clear the Phone field on Contact when the Do Not Call checkbox is checked. A record-triggered Flow can run when a Contact is created or updated, check whether Do_Not_Call is true, and then update the triggering Contact record by setting the Phone field to blank. Salesforce Flow supports updating records, including directly updating the record that triggered the flow.

B. Validation rule is incorrect because it can block a save but cannot delete or clear the Phone field automatically.

C. Quick action is manual, not automatic.

A. If-then rule is not the best current Salesforce automation tool for this requirement.
