Toppr Admin · Accepted Answer

Fibre is the basic unit of raw material having suitable length, pliability, and strength for conversion into yarns and fabrics/material/cloth.

A fibre of extreme length is a filament. Fibres can occur naturally or can be produced artificially.

Here, X is a fibre, Y is the cloth/fabric/material. Z is the natural fibre and W is the artificial or human-made fibre.

paper/book is an example of products of natural polymer (cellulose), pen is an example of industrial product of synthetic polymer.

Therefore, option A is correct.
