A charged particle entering in a region having uniform electric field $\overrightarrow{E}$   and uniform magnetic field $\overrightarrow{B}$  with velocity ${\overrightarrow{v}}_0$  goes undeflected. Select the possible case(s).

Either $\overrightarrow{E}=0or\overrightarrow{B}\left|\right|\overrightarrow{E}$

A) When velocity is not parallel to electric field, the charge will deflect along the electric field.

B) Here there will not be any magnetic force acting on the charge, but the electric field will deflect from its path, as they are not parallel.

C) There is a possibility of cancelling of electric force and magnetic force on the body, as they are not parallel.

D) The charged particle will get accelerated in the direction or opposite to the electric field and will not be deflected by the magnetic force, as they are parallel.
