Solution

The correct option is B Anaerobic respiration
During strenuous exercise like sprinting, the need for energy
in muscles increase and the oxygen availability decreases.
In such cases, the muscle cells meet the energy requirement by the anaerobic respiration and lactic acid is formed in the muscle cells.
