For a short dipole placed at origin O, the dipole moment P is along $\displaystyle x$-axis, as shown in the figure. If the electric potential and electric field at A are $\displaystyle \mathrm{V}_0$ and $\displaystyle \mathrm{E}_0$, respectively, then the correct combination of the electric potential and electric field, respectively, at point B on the $\displaystyle y$-axis is given by
