Statement $I$: Among $Zn$,$Mn$,$Sc$ and $Cu$,the energy required to remove the third valence electron is highest for $Zn$ and lowest for $Sc$.
Statement $II$: The correct order of the following complexes in terms of $CFSE$ is $[Co(H_2O)_6]^{2+} < [Co(H_2O)_6]^{3+} < [Co(en)_3]^{3+}$.

• A
  Both Statement $I$ and Statement $II$ are true
• B
