Solution
The correct option is B Lactic acid
Anaerobic respiration is the breakdown of glucose in the absence of oxygen. In humans, oxygen-starved muscle cells will respire anaerobically under stress such as heavy physical activity. The by-product of anaerobic respiration in muscles is the lactic acid which causes the puffed out feeling. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.
So, the correct answer is 'Lactic acid'.
