Assertion A and the other is labelled as Reason R.
Assertion A: $\left[\mathrm{CoCl}\left(\mathrm{NH}_3\right)_5\right]^{2+}$ absorbs at lower wavelength of light with respect to $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5\left(\mathrm{H}_2 \mathrm{O}\right)\right]^{3+}$
Reason R: It is because the wavelength of the light absorbed depends on the oxidation state of the metal ion.
Select the correct option:
