C)NAD+ is more reduced than NADH. 
D)Oxaloacetate is more reduced than malate.

Quizplus · Accepted Answer

The reaction involves the conversion of malate to oxaloacetate, indicating a loss of electrons. Therefore, malate is more reduced than oxaloacetate. NAD⁺ is the oxidizing agent, meaning it accepts the electrons lost by malate to become reduced to NADH. This makes choice C incorrect. The reduction state of oxaloacetate is not mentioned in the reaction, making choice A and D irrelevant.
