Solution

The correct option is A Parabola
The accleration of the electron will be $- \frac{e E}{m}^j$
This is a constant acceleration.
The motion will be analogous to a mass projected horizontally with velocity $v_{o}$ with gravity acting in the vertical direction. We know that motion of such a mass is a parabola. Hence, correct option is A.
