Solution

The correct option is B Oxidative decarboxylation
The end product of glycolysis, pyruvic acid is converted to acetyl coenzyme-A by the process of oxidative decarboxylation in presence of pyruvate dehydrogenase enzyme. This acetyl-CoA then enters Krebs' cycle where it is oxidized to produce energy in the form of ATP.
Thus, the correct answer is option D.
