Explanation:
Detailed explanation-1: -The correct answer is Collagen. Collagen fibers are present in the bones and these give strength to the human bones.
Detailed explanation-2: -Both bone and cartilage use mainly collagen and elastic protein fibers in their extracellular matrix, but cartilage uses a ground substance rich in the carbohydrate hyaluronan and bone uses a ground substance rich in a mineralized calcium phosphate compound known as hydroxyapatite.
Detailed explanation-3: -Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress.
