Solution
The correct option is D Diaphragm
The diaphragm is a thin skeletal muscle that sits at the base of the chest cavity and separates the abdomen from the chest. When we inhale, it contracts and the air moves into the lungs. When we exhale, it relaxes thereby pushing air out of the lungs. Hence, the diaphragm forms the floor of the chest cavity.
So, the correct answer is option C.
