The correct option is C Bone will become unfix
A ligament is the fibrous connective tissue that connects bones to other bones. When ligaments are damaged or cut, the knee joint may become unstable. Ligament damage often occurs from a sports injury. A torn ligament severely limits knee movement that is the bone is fixed, resulting in the inability to pivot, turn, or twist the leg. Surgery is an option to repair a torn ligament if another medical treatment is not effective.
