Question

Sweater used in winters is made up of:

• A. cotton
• B. jute
• C. wool
• D. silk

Answer 1

The correct option is C wool

Wool is obtained from sheep and yak hair. These fibres are flexible with tons of tiny air pockets. These pockets acts as a blanket from the cold. This keeps the body warm in winters.

Cotton and silk are also used for making fabrics but they do not have the air pockets to trap air.

Jute is rough and uncomfortable to wear, hence cannot be used to make sweaters.
