Polar molecules are the molecules :

(1) having zero dipole moment.

(2) acquire a dipole moment only in the presence of electric field due to displacement of charges.

(3) acquire a dipole moment only when magnetic field is absent.

(4) having a permanent electric dipole moment.

Correct answer: (4) having a permanent electric dipole moment.

Explanation:

Polar molecules have centres of positive and negative charges separated by some distance, so they have permanent dipole moment.
