The correct answer states D. This is not accurate.

"Preferred Channel Marks are found at junctions of navigable channels and often mark wrecks or obstructions. A vessel may normally pass this aid on either side, but the top color band indicates the preferred channel. If the top band of the aid is red, it is treated as a red mark and kept to starboard as the vessel passes it while returning from sea."

No it says C......I've had USCGQ highlight the wrong answer several times now. Please check for the glitch.
