They are mostly found in the fibrous tissues such as skin, ligaments, and tendons. This type of protein helps to support and strengthen the tissues.

Option c. is given as “collagen”.

Collagen is the most abundant protein in our body, which constitutes about 25% to 35% of the entire body protein content.

Hence, the correct answer is option c.
