@KuldeepJaidev by Faraday's law we have w=zit
Current and time is same so we check by z
Z=mm/vf*96500
So check the ratio of molar mass / valency factor for each option, the one with maximum ratio is your answer
Valency factor you can easily check which comes out to be 2 2 1 2 respectively
So answer comes out to be C
