Neutron cannot be accelerated in a magnetic field.
Magnetic field is the region of space near a magnetic material or moving charged particle with in which a magnetic force of magnetism act. It is a vector quantity.
Now lets check all options one by one
Option (A): Alpha particle
Alpha particles are charged particles in magnetic field so the particles deflected. Alpha particles are positively charged.
So it is incorrect option.
Option (B): Beta particle
Beta particles are charged particles in magnetic field so the particles deflected. Beta particles are negatively charged.
So it is incorrect option.
Option (C): Neutron
Neutrons does not have any charge so the particles are not deflected in magnetic field.
So it is correct option.
Option (D): Proton
Proton are charged particles in magnetic field so the particles deflected.
So it is incorrect option.
Thus, from the above conclusion we can say that Neutron cannot be accelerated in a magnetic field.
