In passing \( 3 \mathrm{~F} \) of electricity through the three electrolytic cells connected in series containing \( \mathrm{Ag}^{+}, \mathrm{Ca}^{2+} \) and \( \mathrm{Al}^{+3} \) ions, respectively. The molar ratio in which the three metal ions are liberated at the electrodes is
(A) 1: 2: 3                             
(B) \( 3: 2: 1 \)
(C) \( 6: 3: 2 \)                       
(D) \( 3: 4: 2 \)
