The correct choice is (a) 2 GTPs

To explain I would say: The primary products of the TCA cycle pathway are the reduced coenzymes, NADH and FADH2, which contain high energy electrons removed from various substrates as they are oxidized. The Krebs’ cycle produces two GTP molecules during one cycle. 2 GTP molecules equivalents to 2 ATP molecules.
