choose the correct option and rewrite the complete statement

Explanation:

on adding zinc to CuSO4 solution, zinc displaces copper from copper sulphate & forms zinc sulphate solution because zinc is more reactive metal which displaces less reactive metal from its solution.

This is indicated by a colour change from blue to colourless.

CuSO4 solution has a blue colour while ZnSO4 solution is colourless.
