A moving charge particle enters a uniform magnetic field perpendicular to the direction of field. Then it follow a circular path.

The magnetic field perpendicular to velocity. So, the particle will perform a uniform circular motion and thus speed will not change and thus no change in kinetic energy.

Option (C) is correct.
