Solution

The correct option is A Collagen
Connective tissues provide the structural framework of a cell. These are responsible for support and mechanical strength. It has great tensile strength. It is the main component of fascia, cartilage, ligaments, tendons, bone, and skin. Along with soft keratin, Collagen is responsible for skin strength and elasticity and its degradation leads to wrinkles that accompany ageing.
Thus, the correct answer is option A.
