C. A boat is moving directly away from you.

Answer :

Final answer:

Seeing red, green, and white lights on another boat indicates a head-on approach.


Explanation:

When you see a red, a green, and a white light on another boat, it indicates that the boat is approaching you head-on. The red light signifies the port (left) side of the boat, the green light indicates the starboard (right) side, and the white light is seen from the stern of the boat. This arrangement helps determine the direction of the approaching vessel.
