The correct option is D Yacht
A yacht is any sail or power vessel used for pleasure, cruising, or racing. It is lightweight, too. Hence, Option C is correct. Among the rest of the options, dinghy means an open boat with a mast and sails, canoe means a light, narrow boat with pointed ends and no keel, propelled with a paddle or paddles, frigate means a sailing warship. These options do not express the intended meaning, hence incorrect.
