BOTH INTERNATIONAL & INLAND Which lights must a vessel being towed show at night?

A a white all-round light, only
B a flashing yellow light, only
C sidelights and a stern light
D forward and after masthead lights
AI Explanation

The correct answer is C) sidelights and a stern light. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a vessel being towed must show sidelights (red and green) and a stern light (white) at night. These lights help other vessels identify the towed vessel and its orientation. The other options are incorrect because a white all-round light or a flashing yellow light are not the required lights for a vessel being towed, and forward and after masthead lights are not the correct configuration.
