Solution

The correct option is D Succinic acid to fumaric acid
Krebs's cycle is also called as TCA cycle. In this, succinic acid is converted into fumaric acid by enzyme succinate dehydrogenase. In this step, FAD acts as electron acceptor and is converted into FADH2.
Thus, the correct answer is 'Succinic acid to fumaric acid.'
