The correct answer is:
If both assertion and reason are true and reason is the correct explanation of assertion.
Electropositive elements like zinc precipitate copper from a solution of copper sulphate and finally forms a complex.
\(\mathrm{CuSO}_4+\mathrm{Zn} \rightarrow \mathrm{Cu}+\mathrm{ZnSO}_{4(a q)} \rightarrow\left[\mathrm{Zn}\left(\mathrm{H}_2 \mathrm{O}\right)_4\right] \mathrm{SO}_4\)
\(\mathrm{CuSO}_4+\mathrm{Zn} \rightarrow \mathrm{Cu}+\mathrm{ZnSO}_{4(a q)} \rightarrow\left[\mathrm{Zn}\left(\mathrm{H}_2 \mathrm{O}\right)_4\right] \mathrm{SO}_4\)
