Question 941 Deck General

The correct answer is C) One red light. The United States Coast Guard requires vessels engaged in bunkering operations at a dock to display a single red light at night. This signal is specified in the Code of Federal Regulations (CFR) Title 33, Section 156.120, which states that a vessel must display "a red light" during the transfer of oil or hazardous material. The other answer choices are incorrect because they do not match the specific signal required by the regulations. Displaying two red lights or a combination of red, yellow, and white lights would not fulfill the regulatory requirement for a single red light during bunkering operations.
