D Correct answer
Explanation

Forced exhalation is an active process that requires the contraction of accessory expiratory muscles. The internal intercostal muscles contract to depress the rib cage, while abdominal muscles (like the rectus abdominis and obliques) contract to push the diaphragm upward, reducing thoracic volume.
