C Correct answer
Explanation

Only charged particles can have their kinetic energy increased in a particle accelerator. Electric and magnetic fields are used to speed up the particles and these field have no effect on uncharged particles. Neutrons have no charge so a particle accelerator can not increase the kinetic enegy of a neutron.
