Solution

The correct option is C
Statement I:- False

Statement II:- True

Polymers are classified into fibres, plastics, and elastomers on the basis of the force of attraction between different molecules that combine to form polymer chains. So all plastics (thermoplastics and thermosetting plastics), natural and synthetic fibres belong to the category of polymers.

Rubber is an elastomer as it has elastic properties. It is a polymer which is formed by the combination of monomer units i.e. isoprene.
