Solution

The correct option is D Statement I is False and Statement 2 is True.
In an external field, Both experiences different amount of forces, $α$ particle experiences twice the force but the mass of $α$ particles are huge as compared to $β$ particles which are nothing but electrons. so, both experiences different deflections.
For case of specific charge, in $α$ particles the q/m ratio is very low as compared to $α$ particles while charge on $α$ particle is just twice that on $β$ particle.
