Answer

[(A)PQ(B)PRS(C)PT(D)PQRST]

Explanation

(A) If velocity is along electric field path will be straight line otherwise parabolic
(B) In magnetic field straight line, parabolic circular paths are possible
(C) if `qE=qVB` then path will be straight line and if EF and magnetic field parallel to each other then path will be helical.
(D) if any net constant force like gravity, electric force e.t.c then path could be St. line, parabola, circlar and helical (helical path can be possible if magnetic field is applied).
