AI Explanation
The correct answer is A) Opening and closing the throttle. An airplane should not send this signal in reply to a surface craft because it could be misinterpreted as an emergency signal. The proper signals for an airplane to use in communication with a surface craft are rocking the wings (B), flashing Morse code T (C), or flashing the navigational lights off and on (D). These visual signals are the standard methods for an airplane to communicate with a surface vessel and do not risk being confused with an emergency transmission.
