A
no signal is required.
B
four short blasts
C
one long blast
D
one prolonged blast
AI Explanation
The correct answer is D) one prolonged blast. According to the U.S. Coast Guard regulations, a power-driven vessel that is leaving a dock or berth while operating in inland waters is required to sound one prolonged blast as a signal. This signals to other vessels in the area that the vessel is getting underway. The other answer choices are incorrect because: A) no signal is required is wrong, as the regulations do require a signal. B) four short blasts and C) one long blast are not the correct signals specified in the regulations for this situation.
