On a straight-in approach, what is the correct action regarding the procedure turn?

On a straight-in approach, the correct action is to not perform the procedure turn because the procedure is designed to allow the pilot to approach the airport directly from the established route without the need for a turns. The straight-in approach does not require the additional maneuver of a procedure turn that is typically used to transition from an en route phase to a landing phase when making a turn to align with the final approach course.

A procedure turn is generally associated with standard approaches when precise alignment with the runway is necessary, and is only performed when the approach plate specifically indicates that it is required. In this case, since a straight-in approach is being conducted, the pilot is already aligned with the final approach path, thus avoiding the need for a procedure turn altogether.

The other options may imply actions that add unnecessary steps in the landing process, which could complicate the approach and potentially jeopardize safety by delaying the descent or creating unnecessary maneuvering in the airspace. Therefore, the phrase "do not perform the procedure turn" aligns accurately with the standard operating procedures for straight-in approaches.
