detailed solution

Correct option is A

Iron in FeH2O5NOSO4 exists in +2 oxidation state having electronic configuration (3d)6. The unpaired electron of NO is shifted to Fe2+ changing it to Fe+ and also changes NO to NO+. The electronic configuration of iron in the complex thus becomes (3d)7 with three unpaired electrons as in the complex, sp3d2-hybridization exists.
