Explanation:
When reading the passage, we understand that the author opposes the first sentence. The second sentence would effectively validate the first statement if it were correct, in which case, it would make the author's point invalid.

C is not correct since the author thinks the first sentence is invalid, but the second sentence does not validate that sentence.
D is not correct since both the first and second sentences oppose the author's opinion.
