The term "final solution" has been extensively associated with the Holocaust, and therefore it carries a lot of negative connotations. To avoid using this term, we can use alternatives like "ultimate answer," "conclusive resolution," "definitive outcome," or "last resort." These synonyms convey the same sense of finality or permanence, but without evoking the appalling historical context of the phrase. Alternatively, we may also use more specific terms to describe a particular type of final solution, such as "endgame plan," "ultimate remedy," "decisive settlement," or "terminal measure." Regardless of the synonym chosen, it's essential to remember that words have power, and we must use them with care and responsibility.
