Equal quantities of electricity are passed through three voltameters containing `FeSO_(4), Fe_(2)(SO_(4))_(3) and Fe (NO_(3))_(3)`. Consider the following statements in this regard.

A

the amount of iron deposited in `Fe_(2)(SO_(4))_(3) and Fe(NO_(3))_(3)` is equal

B

the amount of iron deposited in `Fe(NO_(3))_(3)` is two third of the amount of iron deposited in `FeSO_(4)`

C

the number of iron deposited in `FeSO_(4) and Fe_(2)(SO_(4))` are equal

D

the amount of iron deposited in `Fe(NO_(3))_(3) and FeSO_(4)` are equal
