Match the entries of column I with column II.
$$\begin{array}{cc}\text{Column A}& \text{Column B}\\ \text{(a) Semi-synthetic fibre}& \text{(i) Cellulose}\\ \text{(b) Elastomer}& \text{(ii) Nylon}\\ \text{(c) Synthetic Fibre}& \text{(iii) Rayon}\\ \text{(d) Biopolymer}& \text{(iv) Rubber}\end{array}$$

The correct option is C

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

Rayon:- It is a semi-synthetic fibre because it is produced by the chemical synthesis of cellulose which is present in plants.

Rubber:- It is a natural polymer with elastic properties and hence it belongs to the category of elastomers.

Nylon:- It is the first artificially prepared fibre.

Cellulose:- It is made of repeating units of the monomer, glucose. It is found in all plants naturally. Hence it is called a biopolymer.
