A "I intend to intend to overtake you on your port side"
B "I am intend to leave you on my starboard side"
C "I am altering my course to port"
D None of the above
AI Explanation

The correct answer is D) None of the above. The one short blast of the whistle does not have the meaning of any of the provided answer choices. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a one short blast of the whistle is used to indicate "I am altering my course to starboard". It does not signal any intention to overtake or leave the other vessel on a particular side. The other answer choices do not accurately reflect the meaning of the one short blast whistle signal in the given scenario.
