which has highest e/m ratio

a) he 2+



d) he+

e / m ratio is charge by mass ratio. Option (c) is right because mass of hydrogen is 1 and charge is 1, so ratio is 1. While for He2+, charge is 2 and mass is 4, so ratio will be 0.5.

Your question is not very clear. If you mean in terms of electronic charge, the e / m ratio is the same, which is equal to 1.758 X 1011 C/Kg.
