A Correct answer
Explanation

Combing, it is a method for preparing carded fibre for spinning. Combing is divided into linear and circular combing. The Noble Comb is an example of circular combing. The French comb is an example of linear combing. The process of combing is accompanied by filling, a process of evening out carded or combed top making it suitable for spinning. Combing separates short fibres using a rotating ring or rectilinear row of steel pins. The fibres in the 'top' produce have been straightened and lie parallel to each other. When combing wool, the discarded short fibres are called boils and are ground up into shoddy.


Hence, the correct option is $\text{A}$

Silk fibre is drawn from the cocoon of _________.

  1. butterfly

  2. worm

  3. silkworm
  4. both $A$ and $B$
