Solution

The correct option is B
lactic acid

The correct option : B
The explanation for the correct option:
The demand for energy is great during vigorous exercise.
The availability of oxygen to produce energy is restricted.
As a result, anaerobic respiration occurs in the muscle cells to meet the energy need.
Lactic acid is formed in muscles as a result of the anaerobic metabolism of glucose.
Muscle cramps are caused by an accumulation of lactic acid in the muscles.
As a result of the accumulation of lactic acid in the legs after severe exercise, we get leg cramps.
Final answer: During heavy exercise, we get cramps in the legs due to the accumulation of lactic acid.
