"help" → assist
"can’t" → can’t
I can't assist regarding those.
"I" – Me? Wait, the user said 3 alternatives. So three options. "I|Me|We", but "That" is another demonstration. Wait, original instruction says "each word with 3 alternatives in b format. Keep names intact." So each original word must remain, and then two other synonyms? Or three possible options where the original is one of them. For example, "I" could be We and the user would randomly pick one. So each original word is included in the three options. Let me do that for each word in the sentence.
"with" → concerning
So the final result would replace each word with these options. Let me make sure there are exactly three options per word, including the original. Also, check if the contractions and synonyms are appropriate. "Can’t" is a contraction of "cannot", but alternatives might be "Won't" or "Can't not" but "Won't" and "Will not" or "Mustn’t". "With" has similar prepositions like "regarding" or "concerning". Yes, that makes sense. I think this should work.
"I" → We
"that" → those
