Answer Choice D

This is an argument structure/method of reasoning where we are asked to describe the logic in the passage. While the answer choice will be true of the passage, it's not a must be true. Mbts ask us what new fact we can infer from or prove based on the argument, here we are asked to describe the reasoning. D is incorrect because the author reasons by analogy, arguing that one thing is incorrect because it would be incorrect in a similar situation. A counterexample is a fact that directly disproves a statement.

Thank you!
