Explanation:
Evolution is a slow natural process occurring in living organisms which explains the formation of the diversity of organisms on Earth. In simple terms, evolution explains how life survived on Earth after the origin of life but it cannot explain the origin of life. However, modern evolutionary biologists are now trying to decode the origin of life through evolutionary evidence and support that earlier form of life originated in the large oceans around 3.5 billion years ago. These organisms are simple living unicellular organisms which later evolved into the eukaryotic organisms.

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.
