A microscopic reconnaissance drone deployed into the mitochondrial matrix of an active muscle cell tracks a single three-carbon pyruvate molecule entering the inner compartment. The drone observes an enzymatic complex strip away one carboxyl group as waste gas and attach the remaining two-carbon fragment to an organic carrier molecule while transferring high-energy electrons. Based on this observation, what are the primary products directly generated from this single molecule during pyruvate oxidation?

A) One acetyl-CoA, one molecule of carbon dioxide, and one NADH

B) One molecule of lactate, one NAD+, and one ATP molecule

C) Two acetyl-CoA, one molecule of carbon dioxide, and one FADH2

D) One molecule of oxaloacetate, one carbon dioxide, and one ATP
