Which of the following is a thermosetting plastic?

Explanation:
Thermosetting plastics set into a rigid form through a chemical cure that creates a cross‑linked network. Once cured, they don’t melt or soften with heat because the covalent bonds lock the material in place. Epoxy resin does this: when mixed with a hardener, it forms many cross-links, giving a strong, heat‑resistant network ideal for coatings and adhesives. The other materials—acrylic, nylon, and PVC—are thermoplastics; they soften and can be remolded when heated because their polymer chains aren’t heavily cross-linked. So epoxy resin is the thermosetting plastic.
