Option 1 -> "Acquitted from" is not the standard collocation used in English legal terminology.
Option 2 -> "Acquitted of" is the correct prepositional phrase; "of" is always used with "acquitted" when referring to charges or accusations.
Option 3 -> "Acquitted in" is grammatically incorrect; "in" is not used with the verb "acquitted" in this context.
Option 4 -> "Acquitted for" is incorrect usage; "for" does not collocate with "acquitted" when discussing criminal charges.
Hence, Option 2: of -> "Acquitted of" is a fixed collocation in English, particularly in legal contexts, where someone is cleared or freed "of" charges or accusations -> correct
