The correct answer is option (A) abundance of collagen fibers.
Bones are a type of supportive connective tissue forming an integral part of the skeleton. Bone tissue is made up of the different types of bone cells embedded in a matrix.
Bone matrix is mainly composed of the collagen fibres, also known as the ossein. They are fibrous protein units linked together rendering elasticity and improving fracture resistance. Collagen fibres are long, very flexible with a high tensile strength and resist stretching. They impart the characteristic resilience and strength, allowing it to withstand strong tension in case of bones, tendons, ligaments.
