Solution

Zinc is more reactive than copper. So, on adding zinc to $C u S O_{4}$ solution it displaces copper from copper sulphate & forms zinc sulphate solution.

$Z n + C u S O_{4} \to$ $Z n S O_{4} + C u$

This is indicated by a colour change from blue to colourless. $C u S O_{4}$ solution has a blue colour while, $Z n S O_{4}$ solution is colourless.

Therefore, zinc displaces copper from $C u S O_{4}$ solution. The correct answer is copper.
