Answer #1

Option A is right.

explanation : The Krebs cycle has three points where the NAD+ gets reduced into NADH & H+.

Option B is right.

explanation : Oxidative phosphorylation generates majority (26 ATP out of 30 ATP produced) of the energy in the cellular respiration. Oxidative phosphorylation happens in the mitochondria. The purpose of the oxidative phosphorylation is to couple the electron energy into producing adenosine triphosphate (ATP).

FADH2 is a redox cofactor.

Thus, the answer is D.

hope it helps.
