The correct answer is: 4. $Zinc+Copper(II)sulfate\rightarrow Zinc\quad sulfate+Cu$<br /><br />Explanation: A redox reaction involves the transfer of electrons between two species. In the given equations, only equation 4 involves the transfer of electrons, where Zinc (Zn) is oxidized to Zinc sulfate (ZnSO4) and Copper(II) sulfate (CuSO4) is reduced to Copper (Cu).
