Rules of the Road Question 444 diagram
A Sound two prolonged blasts followed by two short blasts
B Sound two short blasts and maintain course and speed
C Do not answer the whistle signal from vessel "B"
D Sound one prolonged, one short, one prolonged and one short blasts
AI Explanation

The correct answer is C) Do not answer the whistle signal from vessel "B". This is the correct answer because according to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel is not required to respond to a whistle signal from another vessel. The COLREGS state that the give-way vessel should take action to avoid collision, but the stand-on vessel (in this case, vessel "A") is not obligated to respond with a whistle signal. The other answer choices are incorrect because sounding any type of whistle signal in response to vessel "B" would not be the appropriate action for the stand-on vessel "A" to take in this situation.
