Solution

The correct option is B
Oxygen

As a general rule, the faster and deeper you breathe, the greater is the air exchange happening in your lungs. Breathing becomes faster if the oxygen content in the air around us decreases or the oxygen supply decreases. This leads to an increase in the rate of oxygen intake by blood and a subsequent increase in the carbon dioxide released.
