Correct choice is (a) Structural Polystyrene

Best explanation: Polystyrene is a plastic polymer made from ethylbenzene. They are brittle, cheap, and are extremely easy to mold. The commonly used polystyrenes are High Impact Polystyrene (HIPS), Acrylonitrile Butadiene Styrene (ABS), and Styrene Acrylonitrile (SAN).
