Given below are two statements, one is labelled as assertion $A$ and the other is labelled as Reason $R$. assertion $A$ : ${[\mathrm{CoCl}{({\mathrm{NH}}_{3})}_{5}]}^{2+}$ absorbs at lower wavelength of light with respect to ${[\mathrm{Co}{({\mathrm{NH}}_{3})}_{5}({H}_{2}O)]}^{3+}$ Reason $R$: It is because the wavelenght of light absorbed depends on the oxidation state of the metal ion. In the light of the above statements,choose the correct answer from the options given below:
