The correct answer is:
paramagnetic $\left[\mathrm{Fe}\left(\mathrm{H}_{2} \mathrm{O}\right)_{5}(\mathrm{NO})\right] \mathrm{SO}_{4}$
Cold FeSO, solution on absorption of NO develops brown colour due to the formation of $[Fe(H_{2}O)_{5}(NO)]SO_4$
$\mathrm{FeSO}_{4}+\mathrm{NO}+5 \mathrm{H}_{2} \mathrm{O} \rightarrow [Fe(H_{2}O)_{5}(NO)]SO_4$
This complex has 3.89 BM magnetic moment shows that it has 3 unpaired electrons
$\mathrm{FeSO}_{4}+\mathrm{NO}+5 \mathrm{H}_{2} \mathrm{O} \rightarrow [Fe(H_{2}O)_{5}(NO)]SO_4$
