Question 626 Rules of the Road

The correct answer is D) All of the above. For a vessel 75 meters in length at anchor, the following rules apply under both the International and Inland Navigation Rules: 1) She may use her working lights to illuminate her decks (Option A is correct). 2) She must show an all-round white light forward (Option B is correct). 3) She must show a second all-round white light aft (Option C is correct). All three of these requirements are stated in the navigation rules for a vessel of this size at anchor, which is why Option D, "All of the above," is the correct answer.
