The correct option is B

(a) - (iv), (b) -(iii), (c) - (ii), (d) - (i)


Bakelite:- It is the first artificially prepared plastic by Belgian chemist Leo Baekeland in 1909.

Nylon:- It is the first artificially prepared fibre which got its name from the names of the cities, New York and London.

DNA (Deoxyribonucleic acid):- It belongs to the category of biopolymers because it is found in living beings.

Linear Polymer:- Polythene is a linear chain polymer because monomer units (ethene) combine in a linear form to form this polymer.
