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⁻ is 1.74 BM, whereas for [Fe(H₂ O)₆]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:

(D) Both A and R are true but R is NOT the correct explanation of A

(A) Both A and R are true and R is the correct explanation of A
