The correct answer is: Do not possess permanent dipole moments.
Polar molecules are the molecules in which the centres of positive and negative charges are separated even there is no external field. Such molecules have a permanent dipole moment.
e.g., $\mathrm{HCl}, \mathrm{H}_{2} \mathrm{O}$, etc.
Thus, statement given in option (c) is false.
