What Part of the Following Description Is INCORRECT? Contraction of the Diaphragm

What part of the following description is INCORRECT? Contraction of the diaphragm and external intercostal muscles leads to increased volume in the thoracic cavity and the lungs. The increase in volume leads to an increase in intrapulmonary pressure causing air to move into
The lungs.

A) The contraction of the diaphragm and external intercostal muscles leads to a decrease in volume, not an increase in volume.
B) Increases in volume lead to a decrease in pressure, not an increase in pressure.
C) The relaxation, not contraction, of the diaphragm and external intercostal muscles leads to inhalation.
D) Increased volume and decreased pressure cause air to leave the lungs, rather than enter the lungs.
