Coordination Compounds

Given below are two statements, one is labelled as Assertion \(\mathbf{A}\) and the other is labelled as Reason \(\mathbf{R}\).

Assertion A: The spin only magnetic moment value for \(\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]^{3-}\) is \(1.74 \mathrm{BM}\), whereas for \(\left[\mathrm{Fe}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{3+}\) is \(5.92 \mathrm{BM}\).

Reason \(\mathbf{R}\) : In both complexes, \(\mathrm{Fe}\) is present in +3 oxidation state.

In the light of the above statements, choose the correct answer from the options given below:
