The biomolecules of animal hairs are composed of

A. Carbohydrates

B. Nucleic acid

C. Protein

D. Lipids

Dear student 

The hair is made up of 95% keratin, a fibrous, helicoidal protein (shaped like a helix) that forms part of the skin and all its appendages (body hair, nails, etc.). Keratin is synthesized by keratinocytes and is insoluble in water, thus ensuring impermeability and protection for the hair.

So, I think c would be the correct ans.

Good luck 

Cheers
