Solution

The correct option is C Conversion of pyruvate to acetyl Co-A
The pyruvic acid formed during glycolysis enters the mitochondria where oxidative decarboxylation takes place and acetyl Co-A is formed from pyruvate.
This reaction is catalysed by the pyruvic acid dehydrogenase complex and happens in the presence of $N A D^{+}$ and coenzyme-A.
