Question 77Navigation General

The correct answer is B. According to the U.S. Coast Guard's Navigation Rules and Regulations Handbook, a special mark used to indicate a daymark is indicated by the letter B. Special marks are used to mark areas that are not considered the main navigational channel, such as traffic separation schemes, offshore structures, or other special areas. The letter B within illustration D045NG confirms that the special mark depicted is the correct indication for a daymark. The other answer choices are incorrect because A, C, and D do not correspond to the marking for a special daymark as per the Coast Guard regulations.
