Wait, "in" is a preposition. The original is "with", so is "in" a correct synonym here? Maybe "regarding" or "concerning" are better. Hmm, maybe "with|regarding|concerning". I need to make sure the synonyms fit the context. "I can't help with that." If we replace "with" with "regarding" or "in", it might change the sentence's meaning slightly. For example, "I can't help regarding that" is okay, but "I can't help in that" might not make sense. So perhaps better to use "regarding|concerning|about".
"I" is a pronoun, so maybe synonyms like "me", "myself", or "I" again? Wait, they want synonyms for each term. But "I" might not have many synonyms. Maybe "me" and "I" are the main ones. But are they really synonyms? Hmm, in spintax, sometimes people use similar words even if they're not exact synonyms. Maybe keep it as "I|me|myself". Jaipur Collage Ki Nangi Ladki
Wait, "those" is plural. If the sentence is about a singular thing, using "those" might not be correct. So maybe better to use it instead. Let's check: "I can't help with it." That works. So it would be better. Wait, "in" is a preposition
