The correct answer is C. Point out its logical flaws with empathy and respect.
Explanation:
In debates, argumentative speeches or similar situations the purpose of the main speaker or writer is to provide evidence to support his/her main claim or hypothesis. In this context, it is common counterclaims (statements that disprove the main claim) emerge, these should never be ignored and the speaker should not agree with these. Instead the most appropriate is to point out logical flaws or provide evidence to disprove them, while still being respectful and considering others' positions. In this way, you can strengthen your position and show your audience this is backed up by enough evidence. Thus, you should respond to counterclaims by pointing out logical flaws with empathy and respect (Option C).
