The correct answer is option They need more oxygen to function, so gas exchange needs to increase.
As the person starts a physical exercise, the workload of the muscles increase, which produces a higher demand of ATP.

Due to increase in oxygen demand, the lungs do more gaseous exchange, so that the demand of the oxygen can be fulfilled.
