Official USCG Answer & Rule Citation
Correct Answer: Option A — The normally open (NO) "F" contacts are closed.
In a standard reversing motor controller, the 'F' (Forward) contactor coil is energized to close its associated normally-open (NO) power contacts. This completes the circuit to the motor in the forward phase sequence. The 'R' (Reverse) contacts remain open to prevent a short circuit between phases during operation.
