Correct answer: B. a

In a polar molecule, the centre of positive charge does not coincide with the centre of negative charge. This separation of charges is what gives the molecule a permanent electric dipole moment.

Therefore, the statement that the centre of mass of positive charges coincides with the centre of mass of negative charges is incorrect for polar molecules. This property belongs to non-polar molecules.

Statements b, c, and d correctly describe the properties and examples of polar molecules.
