A) coenzyme A

Explanation:

The NADH and FADH₂ are the energy rich molecules which are formed in the processes like glycolysis, TCA cycle and the fatty acid oxidation as they contain pair of electrons which have very high transfer potential.

As a result of the energy produced when these molecules transfer their electrons to the oxygen, ATP is generated by a series of electron carriers which collectively is called electron transport chain (ETC).

The components of chain include Fe-S centers, Non-heme, FMN, coenzyme Q, and cytochromes.

The energy derived from the transfer of electrons is used to pump the protons across mitochondrial membrane.

As a result, an electrochemical gradient is generated which results in some energy which is then harnessed by the ATP synthase to form ATP.
