A charged particle goes undeflected in a region
containing electric and magnetic field. It is possible that
(a) Ê || B, V|| Ê (b) Ê is not parallel to B
(c) V II B but Ê is not parallel to B
(d) E I| B but V is not parallel to Ê
(More than one option is correct)

option a,c is correct
because v || B therefore force due to magnetic field is zero
only force due to electric field acts.
if E is not parallel to B that is if it is perpendicular to B then particle goes undeflected.
