Solution

The correct option is A Citric acid
Citric acid cycle is also called as Krebs cycle or tricarboxylic acid cycle. It is a metabolic cycle through which aerobic organisms obtain their energy. Pyruvate produced in glycolysis first gets converted into acetyl CoA before entering citric acid cycle. This acetyl CoA is accepted by oxaloacetic acid (OAA) to form ctric acid, the first product of the cycle.
Thus, the correct answer is 'Citric acid.'
