Answer: Option B) NADH and FADH2
Explanation:
The purpose of the Krebs cycle is to convert potential chemical energy into metabolic energy in the form of ATP that can be used by the body.
Hence, the products of the Krebs cycle include:
- 3 molecules of NADH, 
- 1 molecule of FADH2,
- 1 molecule of GTP,
- 2 molecules of CO2 
Thus, NADH and FADH2 are two of the products of Krebs cycle.
