Buoys which only mark the left or right side of the channel will never exhibit a light with which characteristic?

AI Explanation
The correct answer is B) Composite group flashing. Buoys that mark the left or right side of a channel (lateral markers) will never exhibit a composite group flashing light characteristic. This is because the composite group flashing pattern is reserved for special purpose buoys, such as those marking wrecks or obstructions, not for standard lateral channel markers. The other answer choices are incorrect because flashing (A), quick flashing (C), and equal interval (isophase) (D) are all light characteristics that can be used on lateral channel marking buoys.
