Solution

The correct option is C Glycolysis.
Pyruvic acid , ATP and energy are the by products of glycolysis which is an essential chemical reaction within the cells for production of energy.
The overall reaction of glycolysis that takes place in the cytoplasm of the cells can be represented as:

C₆H₁₂O₆ + 2 NAD⁺ + 2 ADP + 2 P -----> 2 pyruvic acid, (CH₃(C=O)COOH + 2 ATP + 2 NADH + 2 H⁺
Glucose with six carbons is converted into two pyruvic acid molecules with three carbons each. 2 ATP are produced from glycolysis.
Therefore, the correct answer is option C.
