Solution

The correct option is E Gamma only
Magnetic force acting on a particle $F = q (v \times B)$ where $q$ is the charge of the particle
As both alpha and beta are charged particles whereas gamma is neutral.
$⟹$ Magnetic force on the gamma particle is zero, thus only gamma particle will not be deflected by magnetic field.
