Answer:
A. The runner's muscles have accumulated lactic acid.
Here is an explanation of what happens in the runner's muscle:
It is quite common to feel a burning sensation in the muscles after rigorous exercises. This muscle pain and soreness is due to the accumulation of lactic acid in the muscles.
Lactic acid is formed due to the combustion of carbohydrates in the body in the absence of oxygen. This is called anaerobic respiration.
In normal circumstances, our bodies use the process of aerobic respiration to provide energy. In this process carbohydrates are broken down in the presence of oxygen to produce carbon (iv) oxide, water and energy.
