If a Piece of Greek Text Makes More Logical Sense

If a piece of Greek text makes more logical sense when translated into Aramaic (Jesus' original language) then that particular passage:

A) is a historically reliable witness of the words of Jesus
B) is a historically unreliable witness of the words of Jesus
C) may likely trace back to an Aramaic original, but cannot-based on this alone-serve as evidence of a historically (un) reliable witness of the words of Jesus
D) has been altered for theological purposes
