BOTH INTERNATIONAL & INLAND Which vessel may exhibit a lantern combining the two sidelights and stern light?

Correct Answer: Option A — 10-meter sailing vessel

Rule 25(c) permits a sailing vessel of less than 20 meters in length to combine its sidelights and stern light into a single lantern carried at or near the top of the mast where it can best be seen, simplifying the lighting requirements for smaller recreational or commercial sailing craft.
