Question 2075 Deck General

The correct answer is D) polypropylene. Polypropylene is the lightest of the rope materials listed. It has a specific gravity of around 0.91, which means it is less dense than water and will float. In comparison, nylon has a specific gravity of around 1.14, manila around 1.13, and dacron (polyester) around 1.38. The lower density of polypropylene makes it the lightest rope option among the choices provided. The other materials, while suitable for various maritime applications, are denser and therefore heavier than polypropylene. This makes polypropylene the optimal choice when the lightest possible rope is required.
