Identify homopolymer from following.

Step-by-step solution

Thermocol, also known as expanded polystyrene (EPS), is a homopolymer. A homopolymer is a polymer that is composed of only one type of monomer unit repeated throughout its structure. In the case of thermocol, the repeating unit is the styrene monomer. When polymerized, styrene forms a long chain known as polystyrene, which is used in a variety of applications, including packaging materials like thermocol. Here's a brief description of each option to clarify why the others are not homopolymers: Polycarbonate (Option
