    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 [Fe(CN)6]3−\left\lbrack Fe(CN)_{6} \right\rbrack^{3 -} is 1.74BM1.74BM, whereas for [Fe(H2O)6]3+\left\lbrack Fe\left( H_{2}O \right)_{6} \right\rbrack^{3 +} is 5.92BM5.92BM. Reason RR : In both complexes, FeFe is present in +3 oxidation state. In the light of the above statements, choose the correct answer from the options given below:
