Question

Which of the following is not a synthetic fibre?

• A. Angora
• B. Rayon
• C. Nylon
• D. Polyester

Hint:

Natural fibres come from plants or animals (cotton, wool, silk, angora), whereas synthetic fibres are man-made (nylon, polyester, rayon).

Answer 1

The Correct Option is A

Step 1: Recall the classification of fibres. Fibres are broadly classified into:

Natural fibres (obtained from plants or animals)
Synthetic fibres (man-made fibres)
Step 2: Analyze each option.

Angora: A natural fibre obtained from the hair of Angora rabbits — not synthetic
Rayon: Man-made fibre derived from cellulose — synthetic (semi-synthetic)
Nylon: Fully synthetic fibre
Polyester: Fully synthetic fibre
Step 3: Final conclusion. The fibre which is not synthetic is Angora. \[ \boxed{\text{(A)}} \]
