C is the correct answer.

The correct answer is:
✅ C. Flow Builder

Explanation

The requirement is:
When the Account Status changes to "Audited", automatically update the Audited Date field with today's date.
This is a classic record-triggered automation scenario.
Flow Builder is the recommended tool for this because:

It can run after-save on Account updates.
It can check if Status = 'Audited'.
It can update the Audited Date field with TODAY().




❌ Why not the others?

A. Approval Process → Used for approvals, not simple field updates.
B. Formula Field → Formula fields are read-only and cannot update other fields.
D. Validation Rule → Enforces data entry rules, does not update fields.

I agree its C

it's C. Flow Builder with record-triggered automation is the correct tool for simple field updates based on field value changes.
