Solution
The correct option is D Larynx
The ribs, intercostal muscles and the diaphragm are the structure that play the most important role in the mechanical aspect of breathing, by causing expansion and contraction of the thoracic cavity to facilitate breathing. The larynx or voice box is part of the respiratory tract, but is not involved in the mechanics of breathing.
