BOTH INTERNATIONAL & INLAND Which statement is TRUE concerning a towing light for a vessel towing astern?

Correct Answer: Option C — The towing light is shown above the stern light.

Rule 24(c) mandates that the towing light must be displayed in a vertical line above the stern light. This arrangement ensures that the towing light is visible to vessels approaching from astern, clearly indicating the towing operation while maintaining the required stern light for standard navigation and collision avoidance.
