Under the IALA-B Buoyage System, a buoy displaying a red light will _______________.

AI Explanation
The correct answer is C) be left to starboard when entering from seaward. Under the IALA-B Buoyage System, a red buoy displaying a red light indicates that the buoy should be left to the starboard (right) side when entering a harbor or channel from the open sea. This is a fundamental principle of the IALA-B system, which is designed to provide a consistent system of buoyage for vessels navigating coastal and inland waters. The other answer choices are incorrect because: A) a radar reflector is not a requirement for a red buoy, B) buoys are not typically lettered, and D) the Morse Code "A" light characteristic is not associated with red buoys in the IALA-B system.
