Solution

The correct option is B Cartilage
  • Bones form the endoskeleton in humans and are comparatively harder than cartilage.
  • Cartilage is a flexible connective tissue found in many parts of the body. It can bend a bit but resists stretching.
  • Its main function is to provide support and maintain the shape of flexible body parts like our external ears, nose, and larynx.
  • The ligament is the fibrous tissue that connects bones to other bones.
  • Tendon is a tough band of fibrous connective tissue that connects muscle to bone.

Thus, the correct answer is option B.
