Where, e = charge

m = mass

For the given options:

Option 1.

Charge on this atom = 1e

Mass on this atom = 2m

The ratio becomes:

 

Option 3.

Charge on this atom = 1e

Mass on this atom = 4m

The ratio becomes:

 

Option 2

Charge on this atom = 1e

Mass on this atom = 1m

The ratio becomes:

 

Option 4.

Charge on this atom = 2e

Mass on this atom = 4m

The ratio becomes:

 

As, the mass of hydrogen ion is the least in the given options, so its specific charge (e/m ratio) will be the maximum.

Hence, the correct option is option 2.
