IN REGION A of the IALA Buoyage System, when entering from seaward, the starboard side of a channel would be marked by a _______________.

A red conical buoy
B green can buoy
C red can buoy
D green conical buoy
AI Explanation

The correct answer is D) green conical buoy. In the IALA Buoyage System Region A, when entering a channel from seaward, the starboard side of the channel is marked by green conical buoys. This is the standard practice to help mariners identify the correct side of the channel to navigate through. The other answer choices are incorrect because red conical buoys (A) mark the port side of the channel, red can buoys (C) also mark the port side, and green can buoys (B) mark the starboard side but are not the correct shape for the Region A system.
