Correct match is
Reason : Addition of non-volatile solute into solvent results into depression of freezing point of the solvent.
Assertion $A$ : $\left[ CoCl \left( NH _3\right)_5\right]^{2+}$ absorbs at lower wavelength of light with respect to $\left[ Co \left( NH _3\right)_5\left( H _2 O \right)\right]^{3+}$
Reason $R$ : It is because the wavelength of the 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 :
