A Correct answer
Explanation

Ultra-high-molecular-weight polyethylene (UHMWPE) is used in bulletproof vests and armor due to its exceptional strength-to-weight ratio and impact resistance. It absorbs and disperses kinetic energy from projectiles. Polyamides (nylon) are strong but less impact-resistant, PVC is rigid, polycarbonates are impact-resistant but not used for ballistic protection.
