Given below are two statements, one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A:$ The spin only magnetic moment value for $\left[ Fe ( CN )_6\right]^{3-}$ is $1.74 BM$, whereas for $\left[ Fe \left( H _2 O \right)_6\right]^{3+}$ is $5.92\,BM$.
Reason $R :$ In both complexes, $Fe$ is present in +3 oxidation state.
In the light of the above statements, choose the correct answer from the options given below:
