Solution

The correct option is B During exhalation, chest width decreases.
During inhalation, the ribs move up and outwards, and the diaphragm moves down. This movement increases the space in the chest cavity and air enters into the lungs.
During exhalation, the ribs move down and inwards, while the diaphragm rises up. This reduces the size of the chest cavity and air is pushed out of the lungs.
