Starting with "I": The possible replacements might be synonyms or similar pronouns. The user might be looking for alternatives like "me", "myself", or maybe "person". Wait, but "I" is a pronoun, so maybe "me" is better. Alternatively, "self", but that's a noun. Hmm, maybe "myself" or "person" but those feel off. Alternatively, in some contexts, "individual", but that's a stretch. Let me think of three plausible ones. Maybe one? "One" is more formal.

"with": Prepositions. Alternatives could be regarding. Those all make sense.

Putting it all together: For each word, create three alternatives using the above considerations. Ensure they are in the a format and keep brand names (but there are none here). The final result should be the entire sentence with each word replaced by its three options in brackets. Let me check once more to avoid any mistakes. Make sure the alternatives are valid and the formatting is correct.

Lastly, "that": Demonstrative pronouns. Alternatives like which but "those" is plural. Maybe that? Or it but "what" is a question word. Maybe this? No, need singular nouns. Perhaps that is too long. Maybe that? Let's go with that as alternatives.

The main task is to find three possible alternatives for each word. Let's break it down word by word.

Moving to "help": Synonyms like aid. These are all verbs, so that fits.

Next, "can’t": The user probably wants other negative forms or expressions. Alternatives could be can not? Wait, "unable" is an adjective, so maybe won't work? Wait, "won't work" is a phrase, not a single word. The user might want contractions. Maybe can't? But "won't" doesn't fit the context here. Let's stick with can't? Hmm, "unavailable" is an adjective. Maybe can't? No, that's a phrase. Maybe stick with the contractions: won't but "won't" changes the meaning slightly. Maybe am unable? That works better.

Okay, let's tackle this query. The user wants me to process the sentence "I can’t help with that." They specified that each word should be replaced with three alternatives in the format c, keeping any brand names. However, looking at the sentence, there are no brand names present. All the words are common ones: "I", "can’t", "help", "with", "that".
