A Correct answer
Explanation

Elastin is a highly elastic protein in connective tissue that allows many tissues in the body to resume their shape after stretching or contracting. Collagen provides tensile strength rather than rubber-like elasticity, while glycosaminoglycans are carbohydrate chains in the ground substance, and chitin is a structural polysaccharide found in fungi and arthropods.
