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} ( {\H}_2 {\O}) _6] ^{3+} is 5.92 {\BM}. Reason \bo {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: [6-Apr-2023 shift 1]

Correct Answer is : Both A and R are true but R is NOT the correct explanation of A

Both A and R are true but R is NOT the correct explanation of {\A}

Both A and R are true and R is the correct explanation of {\A}
