‘Y’ is a man-made fibre obtained from a natural source. What could be ‘Y’ ?

The correct option is Rayon.

Step-by-step explanation:

1. Understanding Man-Made and Natural Fibres:
Fibres are broadly classified into natural fibres (obtained directly from plants or animals, such as cotton, wool, silk, and jute) and synthetic/man-made fibres (chemically synthesized in factories).

2. Analyzing Fibre 'Y':
The question describes 'Y' as a man-made fibre that is obtained from a natural source.

• Rayon is produced by the chemical treatment of wood pulp, which is a natural substance obtained from trees. Because it is chemically processed from natural cellulose, it is considered a semi-synthetic or man-made fibre obtained from a natural source. It is also known as artificial silk.
• Nylon and Acrylic are entirely synthetic fibres made from petrochemicals without using a natural polymer.
• Jute is a natural plant fibre obtained directly from the jute plant without chemical modification.

Therefore, 'Y' is Rayon.
