The correct option is D Ligament break
Tendon is a tough fibrous connective tissue which connects muscle to bone. As two bones are dislocated so, tendon break is not possible.
Skeletal muscle helps to maintain the structural framework of the body. Due to breakage of skeletal muscle 2 bones cannot be dislocated.
Areolar tissue is found in bone marrow. It fills the space inside the organ, supports the internal organ and also helps in tissue repair.
The ligament is a fibrous connective tissue, which connects bone to another bone. Hence, breakage of the ligament can be the reason for dislocation. Therefore, option C is correct.
