Answer 1

The correct option is C Both the statements are true

Diaphragm is a muscular wall that sits at the base of the chest and separates the thoracic cavity, containing the heart and lungs, from the abdominal cavity and performs an important function in respiration. As the diaphragm contracts, the volume of the thoracic cavity increases and the air is drawn into the lungs.
