Solution

The correct option is C

Here the dipole and hence its dipole moment is aligned anti parallel to the external increasing field. Since the negative charge is in the stronger field the force on negative charge F=-|q| E exceeds the force on positive charge.

The net resultant force is directed anti- parallel to the direction of electric field.
