Question 103 Deck General

The correct answer is D) Backstay. A backstay is part of a vessel's standing rigging, which refers to the fixed ropes or wires that support the masts and spars of a sailing vessel. The backstay provides longitudinal support to the mast, keeping it upright and in the proper position. The other answer choices (topping lift, downhaul, and sheet) are all parts of the running rigging, which are the lines used to control the sails and move them as needed, rather than providing structural support to the mast.
