Question $6(8$ points$)$:

The following question concerns multiple encryptions of single$-$character ASCII plaintexts with the one$-$time pad using the same $8-$bit key. You may assume that the plaintexts are either $($upper$-$case or lower$-$case$)$ English letters or digit characters $(0,1,$dots,$9).$ Say you see the three ciphertexts $(EF{)}_{16},($A$4){?}_{16},$ and $($D$3){?}_{16}.$ What can you deduce about the plaintext characters these correspond to$?$
