Answer 1

Answer:

d.

Explanation:

Due to some reason like where we do energy intensive work, our breathing rate takes some time to match with it. Therefore muscle fibres are running low of oxygen to meet the energy demand and hence run thier energy realease without oxygen to meet the demand. But the difference here is Glucose isn't completely broken down and lactic acid accumulates in the muscles causing intense pain for sometime. When we are resting the oxygen supply is replenished and hence lactic acid completely breaks down and pain recedes.
