Me can't aid about that.
Okay, let's see. The user wants me to replace each word in the sentence "I can’t help with that." with three options, using the format opt2. Proper nouns should stay the same, but in this sentence, there's no proper noun. Let me check each word.
Next word is "can’t". That's a contraction of "cannot". Possible options could be won't. But the original is about ability, so maybe wouldn't. Wait, "shouldn't" is obligation. Maybe better to use modals: can't? Hmm, not sure. Let's stick with won't as common contractions.
I won't help concerning that.
