The correct answer is D; "That bump is a normal part of bone healing at this stage. As your body completes the process, the cells in your bone will gradually remodel it to its previous shape."
Further Explanation:
The "lump" that is located in the bone where the bone is healing is common in breaks. When the body suffers from a broken bone, there are three phases the body goes through. The bone restructures itself and the healing begins with the process called remodeling.
The healing bone goes through three phases called;
*Inflammatory phase
*Repair phase
*Remodeling phase
The "lump" is a callous that has formed and the body will eventually heal itself and the "lump" will disappear.
