Answer 1

We have to remember that the silk may be a proteinaceous animal fibre, it’s one of the higher grade fibre known for its softness, smoothness, lustre and opulent look. It gives comfort altogether weather and it’s the simplest natural fabric within the world. The silk threads are taken out from the cooking by process of cooking.

Complete step by step answer:
Let’s us discuss from the given,
In case of option A, We must remember that the scouring is the process of preparing and washing a batch of raw sheep’s wool to get rid of impurities such as grease, dirt and aunt. Scouring removes all the waxes, pectin, and makes the textile material hydrophilic or water absorbent. Therefore, it’s wont to clean sheared silk.
In case of option B, as we know that the Mulberry leaves, biologists have found the source of silkworm’s attraction to mulberry leaves, their primary food source. The domesticated silk moth no longer occurs naturally within the wild. Therefore, it’s used as food for silkworms.
In case of option C, as we know, Sheep is the major product for wool. Wool consists of protein alongside a little percentage of lipids. Therefore, sheep are wool yielding animals.
Option D: Cocoon may be a protective casing spun from silk. Inside the cocoon, the silkworm changes into a pupa. After around two weeks, the pupa emerges from the cocoon as an adult moth. Therefore, cocoons yield fibres.

So, the correct answer is Option A.

Note: We must remember that the varied sorts of silk are produced through differing types of silkworms. It can be distinguished by lustre and texture. We have to know that the silk is formed by differing types and one common type is that the silk moth mulberry.
