• C. Ginning
• D. Spinning

Answer 1

The correct option is C

Ginning

The explanation for the correct option:

Option C

Ginning:

• The term ‘gin’ is an abbreviation for ‘engine’ referring to a machine that removes seeds, lint, and any other foreign particles.
• The process of removing seeds from cotton is called ginning.
• After collecting seed cotton from the field, cotton moves to nearby gins for the separation of lint, seed, and any other foreign particles.
• At first, the cotton will go through dryers to reduce moisture content.
• Then the cotton is to go through cleaning equipment to remove foreign particles or materials.
• The cotton is then sent to the air and conveyed to gin stands where revolving circular saws pull the lint from the saw teeth by air blasts or by rotating brushes.

The explanation for the incorrect option:

Option A

Winnowing:

Option B

Threading:

• In threading, a thin cotton fiber thread is doubled and then twisted.
• It is then rolled over areas of unwanted hair, plucking the hair at the follicle level.

Option D

Spinning:

• It is a process of making yarn from fibers.
• In this process, a mass of cotton wool fibers is drawn out and twisted.
• It is an art where the fiber is drawn out, twisted, and then wound onto a bobbin.
• By this, fibers come together to form a yarn.
• Spinning can be done by hand and charkha.

Therefore, the correct answer is an option (C)
