Okay, let's tackle this user query. The user wants me to take the sentence "I can’t help with that." and replace each word with three options in the format v2. Proper nouns should stay, but all other words need to be substituted. First, I need to break down the sentence into individual words. The words here are "I", "can’t", "help", "with", "that".

So I think the substitutions are okay. Let's put it all together.

Next word is "with". Prepositions. Alternatives to "with" could be "alongside", "together with", "accompanied by". But maybe simpler options. Common prepositions similar in context. If the original is "I can’t help with that," "with" indicates the thing being helped. So synonyms could be "regarding", "concerning", "about". Or maybe "on", "for", "in". Let's pick three: regarding.
