The answer choice D does not relate well to the inference in the question. Recall, the question stem says: In response to the objection that if individuals obeyed their consciences, they could decide anything, the author argues that the designated decision makers could decide anything, too. Both answer choices C and D are relevant, but you need to decide which one is MORE relevant. Answer choice refers to the idea that the government leader may be better informed, but the decision to follow is still up to the individual. One step further from that is the idea that officials should also follow their conscience (answer choice D). So, answer choice D is one step removed from the question stem and reliant on C being correct -- but C is not reliant on D being correct.
