The correct answer is: parallel to the axis of the dipole and opposite to the direction of the dipole moment $\overrightarrow{\mathrm{p}}$
The resultant intensity at a point on equatorial line is $\overrightarrow{\mathrm{E}} . \overrightarrow{\mathrm{E}}$ is parallel and opposite to direction of $\overrightarrow{\mathrm{p}}$.
