Find the amount of current required to deposit 0.02kg of metal in a given electrolysis for 120 seconds. [electro chemical equivalent of the metal = 1.3 x 10\(^{-7}\)kgC\(^{-1}\)]

An example of a non-rechargeable cell is 

Which of the following graphs correctly represents the variation of mass of a given material deposited with time for constant current in Faraday's Law of Electrolysis?
