Solution
The correct option is B Downward
During inhalation, the diaphragm contracts and moves downwards. This increases the space in your chest cavity into which the lungs expand. The intercostal muscles between the ribs also help in enlarging the chest cavity. Whereas during exhalation the diaphragm relaxes and moves upwards into the chest cavity. The intercostal muscles relax to reduce the space in the chest cavity.
