Choice A only.

Work Step by Step

A stationary charged particle feels no magnetic force, supporting choice A and eliminating choice E. The magnetic force is maximum when the particle moves perpendicular to the magnetic field, eliminating choice B. The magnetic force is always perpendicular to the motion of the particle and to the magnetic field and does no work, so it cannot change the particle’s kinetic energy. This eliminates choices C and D.
