The correct orientation of dipoles in pyrrole and pyridine is

The only correct combination for pyrrole is

The only correct combination for pyridine is -

In each situation of Column - I, two electric dipoles having dipole moments vec (p_(1)) and vec (p_(2)) of same magnitude ("that is" , p_(1) = p_(2)) are placed on x-axis symmertrically about origin in different orientations as shown. In column - II certain inferences are drawn for these two dipoles. Then match the different orientations of dipoles in column - I with the corresponding results in column - II. [In column I the co-ordinates corresponding to the centres of dipoles and dipoles having the same dipole lenght]

Depict the orientation of the dipole in (a)stable and (b) unstable equilibrium in a uniform electric field.

Explain the position (orientations) of a dipole in stable equilibrium, unstable equilibrium.
