In this weakening situation I heard JY say that answer choice D is a rare one that attacks the premise (5:04). Just wanted to know when is it ok or acceptable in a weakening situation to attack the premise.
Can someone please explain to me why A is the correct answer but all others are wrong. I initially chose C, and I don't see how it's wrong.
