Chemistry Question on coordination compounds

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
A ⇒ Spin only magnetic moment of [Fe(CN)6]–3 is 1.73 B.M. and [Fe(H2O)6]+3 is 5.92 B.M.
R ⇒ In both cases Fe have +3 oxidation state
In the light of the above statements, write the detailed answer:

Answer

[Fe(CN)6]–3 : Fe+3 : 3d5 with S.F.L
n=1⇒ n = 1
Magnetic moment = 1.731.73 B.M [Fe(H2O)6]+3 Fe+3 : 3d5 with W.F.L
n=5⇒ n = 5
Magnetic moment = 5.925.92 B.M

Both A & R are correct but R is not the correct explanation \text{Both A \& R are correct but R is not the correct explanation }
