A proton (or charged particle) moving with velocity `v` is acted upon by electric field `E` and magnetic field `B`. The proton will move indeflected if

A

`E` is perpendicular to `B` and `E` parallel to `V`

B

`E` is parallel to `V` and perpendicular to `B`

C

`E` and `B` both are perpendicular to `V`

D

`E,V` and `B` are mutually perpendicular and `V=E//B`
