Solution

The correct option is A $Z n, F e$
These both reactions are displacement reactions. Where oxidation numbers of $X$ and $Y$ are similar to copper. Thus $X$ and $Y$ are $Z n$ and $F e$ respectively.
$Z n + C u S O_{4} \to Z n S O_{4} + C u$
$F e + C u S O_{4} \to F e S O_{4} + C u$
$A l + C u S O_{4} \to {A l}_{2} (S O_{4})_{3} + C u$
$A g + C u S O_{4} \to A g_{2} S O_{4} + C u$
