The correct answer is D. A counterclaim to the idea that most people are moral
Step-by-step explanation:
A counterclaim refers to an argument or statement that serves to rebut or prove as invalid the main argument made by someone else. This usually implies the counterclaim provides some evidence to demonstrate the main argument or idea of another person is not true and show the one's claim is valid. In the case of the excerpt presented the main argument the author presents is that people are moral and do not need any enforcement to act correctly, which is supported by the author using "The Ring of Gyges" as an example. On the opposite, a student states people is evil if there was no one witnessing their actions and explains this claim with another story. This means the second argument aimed at disproving the idea of most people being moral and showing this statement was not true. Therefore, the second argument serves as a counterclaim of the author's argument because it rebuts it or disproves it.
