- APolyvinyl chloride
- BPolyamidesCorrect
- CPolyethylene
- DPolycarbonates
Explanation
Polyamides are the correct choice because this category includes high performance synthetic fibers like Kevlar. Kevlar is a type of aromatic polyamide known as an aramid. It possesses exceptional tensile strength to weight ratio and heat resistance, making it ideal for stopping high velocity projectiles. While polycarbonates are used for bullet resistant glass, polyamides are the primary material used in bulletproof vests and body armor due to their ability to absorb and dissipate the energy of an impact. Polyvinyl chloride and polyethylene are common plastics that do not have the necessary structural properties for ballistic protection.
