In nitroprusside ion, the iron & NO exists as Fe(2) & NO+ rather than Fe(3) & NO.These forms can be differentiated by-
a)estimating the conc. Of iron
b)measuring the conc. Of CN-
c)measuring the solid state magnetic moment
d)themally decomposing the compound

nice one...
13Nitroprusside ion is a complex specie- [Fe(CN)5(NO)]2-
Definitely, none of the specie(s) present inside will give a +ve test as the ions won't separate out ; nor wud heating give ny desired result....
So, the only way left to determine the oxid.n state(s) is by finding out the magnetic moment...Hence (c) is right.
