Solution
The correct option is B Jumping
Breathing rate is maximum in jumping because heart rate is faster during jumping. The muscles need more oxygen and more energy at this time. As the level of activity increases, the breathing rate increases to bring more air into the lungs so that the lungs can pump more oxygen into the blood.
