D Correct answer
Explanation

Anti-ferromagnetic substances are expected to possess paramagnetism or ferromagnetism on the basis of unpaired electrons present in them but actually they possess zero net magnetic moment. This is because of the alignment of dipoles is in a compensatory way so as to give a net zero dipole moment, then we get antiferromagnetic substances (MnO).
