Answer: 
moles
Explanation:
We are given:
Moles of electron = 1 mole
According to mole concept:
1 mole of an atom contains 
number of particles.
We know that:
Charge on 1 electron = 
Charge on 1 mole of electrons = 
The metal being plated has a +4 charge, thus the equation will be:
of electricity deposits = 1 mole of metal
Thus 861.8 C of electricity deposits =
moles of metal
Thus moles of metal should be plated
The answer is a. 1.4
Hope it helps.
