Solution

The correct option is A $2 : 1$
The ratio of specific charge of a proton and α-particle is 2:1.
Specific charge is the ratio of charge to mass.
For proton, specific charge is
$\frac{1}{1} = 1$
For α-particle, specific charge is
$\frac{2}{4} = 0.5$
The ratio of specific charge of a proton and and α-particle is
$\frac{1}{0.5} = 2 : 1$
