A "I intend to leave you on my starboard side."
B "I am altering my course to port."
C "I am altering my course to starboard."
D "I intend to leave you on my port side."
AI Explanation

The correct answer is A) "I intend to leave you on my starboard side." According to the Inland Navigation Rules, two short blasts from a power-driven vessel indicate that the vessel is altering its course to starboard. In the given situation, where the two vessels are meeting and will pass within 1/2 mile of each other, this signal indicates that the vessel is intending to leave the other vessel on its starboard side, which is the correct action to take in a head-on encounter. The other options are incorrect because they do not accurately represent the meaning of the two short blast signal in an inland, head-on encounter scenario.
