$\huge\bf\underline{Question:}$

Silk is produced by....?

$\huge\bf\underline{Answer:}$

(3) Cocoon

$\huge\bf\underline{Explanation:}$

When the silk worm forms a covering around itself by secreting a protein through its head, this is called the cocoon stage. This is the most desirable stage for the silk producers. It is at this time that the cocoons are delivered to the factory by the farmer. These factories are called filature operations.Once the cocoons reach the filature operations they are sorted by color, size, shape and texture.
