Answer:

D. Diaphragm

Step-by-step explanation:

The work of breathing is done by the diaphragm, which is the muscle between the ribs, the muscle(s) in the neck and the abdominal muscles, the diaphragm itself is a sheet of muscle that is the shape of a dome, it separates the chest cavity from the abdomen, and is the most important muscle used for breathing

Hope this helps
