Solution

The correct option is B
inhale

During inhalation, the ribs create more space for the lungs by moving outwards and upwards. The diaphragm also moves downwards and flattens. This increases the space in your chest cavity, into which your lungs expand and the pressure becomes low and the air from the atmosphere moves in.
