d. forced exhalation

C. Forced inhalation

Explanation:

To understand the function of each muscle one has to remember the specific attachment sites to the bone. This muscle, as the name describes, attaches to the sternum, the clavicle and the mastoid apophysis. If the muscle contracts, this will produce a linear pull that will expand the thoracic cavity. Therefore, one can assume this muscle will have a crucial role in forced inhalation.

when a bone is fractured and the doctor align the fractured ends, the process of healing takes place at that area and no growth stimulation at the epiphyseal plate occur, unless it is involved in the fracture, this is only a healing process which has nothing to do with the normal bone elongation which happen at the bone ends at the epiphysis. 
If the epiphysis is damaged because of a combined fracture or infection or improper treatment, the growth of this limb may not be normal. and the other limb just go on growing and no compensation happens at all.
