The X-ray of the fractured bone will show if the ends of the bone are well joined, indicating that sufficient healing has occurred for the cast to be removed. The other options are not necessarily accurate indicators for when the cast can be removed. The remodeling phase of bone healing can take months to complete, a cartilage collar may not be relevant to all fractures, and the duration of cast immobilization can vary based on the severity and location of the fracture.
