Solution

The correct option is B Citric acid
The Krebs cycle which takes place in the mitochondria of the cell helps in generating energy and occurs immediately after glycolysis. The cycle which starts with the 3- carbon molecule called pyruvic acid, breaks it down into acetyl coenzyme A which then further combines with oxalo acetic acid to form citric acid. Krebs cycle is also referred to as citric acid cycle.
Therefore, the correct answer is option B.
