Solution

The correct options are
A FMN
C Complex III
In the electron transport chain, the major function of FMN is the oxidation of NADH to NAD. It is both complex III and FMN that enable the translocation of protons across from the matrix to outer (cytosolic) side.

So, the correct answer is 'FMN' and Complex III'.
