AI Explanation

The correct answer is B) the port side of the channel. Explanation: A buoy displaying a flashing red light indicates the port (left) side of the channel when traveling outbound from a U.S. port. This is in accordance with the U.S. Aids to Navigation System, which uses red buoys to mark the left side of the channel. The other answer choices do not correctly identify the meaning of a flashing red buoy in this context.
