List-I shows four configurations, each consisting of a pair of ideal electric dipoles. Each dipole has a dipole moment of magnitude $$p$$, oriented as marked by arrows in the figures. In all the configurations the dipoles are fixed such that they are at a distance $$2r$$ apart along the $$x$$ direction. The midpoint of the line joining the two dipoles is $$X$$. The possible resultant electric fields $$\vec{E}$$ at $$X$$ are given in List-II.

Choose the option that describes the correct match between the entries in List-I to those in List-II.
