Question

Complete the correlation
Silk worm : Cocoon :: Wool : ___
A) Hair of rabbit
B) Cotton plant
C) Fleece of sheep
D) Jute of hemp.

Answer 1

Cocoon is a protective casing made from silk. Warm clothes worn during winters are mostly made of sheep wool. Cocoon is the larva stage of silk worm.

Complete answer:
Silkworms construct a cocoon made from silk fibers, and inside this they turn into pupa, the stage between larvae and adult moths.
Wool is basically the soft hair that coats and insulates the sheep, goats, etc. Hair grows on the body of sheep, goats, quite similar to human heads.

Option A: Hair of rabbit also known as - Lapin, is the animal fibre obtained from Angora rabbit and other rabbit species. They have coats consisting of protective hair along with a fine insulating undercoat.This option is incorrect.
Option B: Cotton plant - Cotton is a soft and fluffy fiber that grows in a protective covering, around the cotton seeds, of the Gossypium genus. This fiber is almost pure cellulose.
This option is incorrect.
Option C: Fleece of sheep - Sheep and other similar animals have fine thick hair, on their bodies, called fleece. These keep them insulated from the cold winters. Thus, this is the correct option.
Option D: Jute of hemp - The most significant difference between Hemp and Jute is - Hemp is a low-THC (tetrahydrocannabinol) Cannabis plant; and Jute is a fiber from the genus Corchorus.Thus, this option is irrelevant and incorrect.

Thus, the correct option is (C) Fleece of sheep.

Note: Greasy wool can be stuffed into spaces in a coop or shed to keep it safe and insulated from the cold weather. Sheep's wool could also be used as a heavy protective covering (mulch) to keep the plant roots safe from winter frosts.
