Woollen clothes made up of wool are obtained from
- Dog
- Horse
- Sheep
- Cat
Hint:
Wool is the natural source of the fabric in nature which means that this is either obtained from plants or animals in general. woolen clothes are the basic requirements of humans during winter on a large scale.
The correct answer is: Sheep
- Wool, is an animal fiber that forms the protective covering or fleece of hairy mammals such as sheep, goats, and camels. Prehistoric humans who wore sheepskin eventually learned to make threads and cloth from the fiber-covered material, which formed a protective outer layer due to the selective breeding of sheep. Most of the long, coarse hair has been removed, leaving behind an insulating, fluffy undercoat made up of soft, fine fibers.
- Wool is primarily obtained by shearing the fleece of live animals, but the fur of slaughtered sheep is sometimes treated to loosen the fibers, creating an inferior type called drawn wool.
