The Correct Option is A
Solution and Explanation
Polystyrene is a synthetic polymer formed by the polymerisation of styrene monomers.
It belongs to the category of thermoplastic polymers, meaning it softens on heating and hardens on cooling without undergoing any chemical change.
Its structure consists of long linear chains with weak intermolecular forces, which allows the chains to slide over each other when heat is applied.
This property makes polystyrene reusable and mouldable multiple times.
Therefore, polystyrene is a thermoplastic polymer.
