Solution
The correct option is B Ligament breakage
The two long bones in hand are the radius and the ulna. Annular ligament or orbicular ligament is a strong band of fibres present on the head of the radius, which keeps it in contact with the radial notch of the ulna. The person must have broken the ligament, which dislocated these long bones, leading to a fracture. Tendons join skeletal muscles to bone, and a tendon breakage causes inflammation. Breakage of skeletal muscles cannot be responsible for the dislocation of bones as they are joined by ligaments. Areolar tissues are found around muscles, nerves, and blood vessels, and so they are not concerned with bones in any way.
