The best definition of polarisation is(a) Orientation of dipoles in ra

1.	The best definition of polarisation is(a) Orientation of dipoles in random direction(b) Electric dipole moment per unit volume(c) Orientation of dipole moments(d) Change in polarity of every dipoleThis question was addressed to me in an internship interview.I'd like to ask this question from Polarization topic in chapter Electric Fields in Material Space of Electromagnetic Theory
Answer» CORRECT option is (b) Electric dipole moment per UNIT volume The best explanation: The POLARISATION is defined mathematically as the electric dipole moment per unit volume. It is also referred to as the orientation of the dipoles in the direction of applied electric FIELD.
