The correct answer is B) Collagen.
Tendons are tough bands of fibrous connective tissue that connect muscles to bones. They are primarily composed of tightly compacted bundles of collagen fibers.
Collagen is the most abundant protein in the human body and a key structural component of connective tissues, including tendons, ligaments, cartilage, bone, and skin. Elastin is another fibrous protein found in elastic tissues like blood vessels and skin, allowing them to stretch and recoil. Fibrin is a protein involved in blood clotting. Cellulose is a complex carbohydrate that forms the cell walls of plants.
