Lactic acid is taken to the liver by the blood, and either: oxidised to carbon dioxide and water, or

Answer 2

Answer:

Oxygen debt occurs when lactic acid secretes excessively after strenuous activity and body is in the want of oxygen.  Thus the right answer is option C

Explanation:

After a vigorous or strenuous exercise oxygen is needed to create lactic acid and to reconvert it to glucose. Thus the oxygen debt occurs after such activity.

It involves the need of extra oxygen by the muscle to recover the stability after exercise.  With the intake of oxygen by oxygen plus after the activities can be helpful for recovering.
