Cleveland Ohio?

I got this one right on the timed portion. However, answer C is attractive and I'm trying to figure out if the logic I followed as to why I didn't choose C is correct:

C isn't the best argument to weaken Marianne's argument against the order because C is basically just saying "well, even if your humming is involuntary, that doesn't mean your unaware of your humming" AKA I don't care if its involuntary or not, I think you're just lying and trying to use that as a crutch to avoid responsibility. Answer C just boils down to well i think you're lying and you may or may not be humming on purpose etc for xyz reasons to distract. Does this make sense?
