The correct option is A

In plants, photolysis of water takes place and molecular oxygen is made available. It acts as a hydrogen(proton) acceptor.

Cytochrome C, found in mitochondria. It transfers electrons between Complexes III and complex IV.

Pyruvate dehydrogenase is the first component of pyruvate dehydrogenase complex (PDC). The pyruvate dehydrogenase complex contributes to transforming pyruvate into acetyl-CoA by a process called pyruvate decarboxylation. This step connects glycolysis to Kreb cycle.

Oxidative decarboxylation of alpha-ketoglutaric acid, in presence of coenzyme-A, leads to the formation of succinyl Co-A. This is a step of Kreb cycle.
