Given below are two statements:
Statement $I$: Crystal Field Stabilization Energy $(CFSE)$ of $[Cr(H_2O)_6]^{2+}$ is greater than that of $[Mn(H_2O)_6]^{2+}$.
Statement $II$: Potassium ferricyanide has a greater spin-only magnetic moment than sodium ferrocyanide.
In the light of the above statements,choose the correct answer from the options given below:

$CuSO_{4(aq)} + 4NH_3 \rightarrow X,$ then $X$ is

Among the statements $(a)-(d)$,the incorrect ones are:
$(a)$ Octahedral $Co(III)$ complexes with strong field ligands have very high magnetic moments.
$(b)$ When $\Delta_{0} < P$,the $d-$electron configuration of $Co(III)$ in an octahedral complex is $t_{2g}^{4} e_{g}^{2}$.
$(c)$ Wavelength of light absorbed by $[Co(en)_{3}]^{3+}$ is lower than that of $[CoF_{6}]^{3-}$.
$(d)$ If the $\Delta_{0}$ for an octahedral complex of $Co(III)$ is $18,000 \ cm^{-1}$,the $\Delta_{t}$ for its tetrahedral complex with the same ligand will be $16,000 \ cm^{-1}$.

Which statement is wrong?

Excess of $aq. NH_3$ can dissolve

Consider the following complexes:
$(a) \ Na_2[Fe(CN)_5NO]$
$(b) \ [Fe(H_2O)_5NO]SO_4$
