Solution

The correct option is B 2
Under Anaerobic conditions, Pyruvic Acid enters in matrix of mitochondrion and undergoes oxidative decarboxylation to form 2 carbon energy rich compound called Acetyl Co A.

This process utilizes 2 oxygen atoms. Incomplete oxidation of Pyruvate leads to the formation of lactic acid in muscles and formation of ethyl alcohol in yeast as a process of fermentation.
So, the correct answer is '2'
