Which of the following statement is correct for the following complex.$\left[\mathrm{Fe}{\left({\mathrm{H}}_2\mathrm{O}\right)}_5\mathrm{NO}\right]{\mathrm{SO}}_4$

$\stackrel{\mathrm{I}}{\mathrm{Fe}}{\left(H_{2}O\right)}_5\left(\stackrel{+}{N}O\right)\stackrel{++}{]} \to$Hybridisation $: {\mathrm{sp}}^3{\mathrm{d}}^2$

                                   $\to {\mathrm{\mu }}_{\mathrm{eff}} : 3.89 \mathrm{BM}$

                                   $\to$ Inspite of electronic transistion from $\mathrm{NO}$to ${\mathrm{Fe}}^{++}$ ,total number of electrons remain conserved. Hence E.A.N does not change.
