Which statement correctly reflects polypropylene characteristics?

• A. Floats well in water and is highly visible
• B. It is highly resistant to UV and has high elongation
• C. It sinks rapidly in water but has low visibility
• D. It absorbs a lot of water and loses strength quickly

Answer: (A)

Polypropylene is a lightweight, water-repellent material, so it stays afloat because its density is lower than water and it doesn’t soak up water. That buoyancy is a defining practical property, and it can be produced in bright colors to make items highly visible. So the statement that it floats well in water and is highly visible best describes its typical behavior and use. Other descriptions—sinking quickly, absorbing a lot of water, or having inherently high UV resistance—don’t fit as well because PP doesn’t absorb water, only sinks if forced by heavier materials, and UV resistance depends on stabilizers rather than being intrinsic to the polymer itself.
