Answer 1

Hint:People in Ladakh and Tibet domesticate an animal with long fur which is present in these two regions and its wool is regarded as valuable fabric for making clothes for winter. Its wool is commonly present in Ladakh and Tibet.

Complete answer:
Some fibers are naturally obtained from animals which are known as animal fibers and wool is one of the animal fibers which are obtained from animals like sheep, yak, goat, camel etc. People living in Ladakh and Tibet domesticate yak for thousands of years and obtain wool for making warm clothes. Yak wool is warm, soft, absorbs up to 30% of moisture, and is resistant to odor. Depending on the factors like age, breed and sex of the yak, yak wool is of three types which differ greatly in properties and appearance. They are coarse fiber whose size ranges from 70 to 90 microns, mid-type whose size ranges between 20 to 50 microns and down-fiber with size ranging between 16 to 20 microns. Among the three types, the down-fiber is considered as the finest fiber. The harvesting period of yak wool is done annually by combing when yak’s coat falls off between June and July. Yarn produced from yak wool is considered to be one of the most lavish and expensive fibers available.Yak is domesticated in Ladakh and Tibet for its fur and yak wool is commonly found in these two regions.

Hence, the correct answer is option (C).

Note:Yak wool provides more warmth because yak wool fibers are hollow and are capable of trapping air and providing high warmth to weight ratios.
