n = 0, Magnetic moment = 0
Thus, (a) is correct.
(b) Paramagnetic substances are magnetised in a magnetic field in the same direction hence, weakly attracted thus, (b) is correct.
(c) Ferromagnetic substances can be magnetised permanently, thus, given statement is incorrect.
(d) Substances like MnO showing anti-ferromagnetism have domain structure similar to ferromagnetic substances, but their domains are oppositely oriented and cancel out each other's magnetic moment.

The correct statements are:
- Due to the pairing of electrons, magnetic moment is cancelled
- Paramagnetic substances are weakly attracted by magnetic field
- The domains in antiferromagnetic substances are oppositely oriented w.r.t. each other
Explanation:
1. Due to the pairing of electrons, magnetic moment is cancelled:
In an atom, electrons exist in different energy levels or shells. Each energy level can accommodate a specific number of electrons. According to the Pauli Exclusion Principle, no two electrons can have the same set of quantum numbers. Therefore, when an atom has an even number of electrons, they are paired up in opposite spins, resulting in the cancellation of their individual magnetic moments. This is why substances with paired electrons do not exhibit any net magnetic moment and are considered diamagnetic.
2. Paramagnetic substances are weakly attracted by magnetic field:
Paramagnetic substances have unpaired electrons in their atoms. These unpaired electrons have individual magnetic moments, which align themselves with an external magnetic field. As a result, paramagnetic substances are weakly attracted by a magnetic field. However, the attraction is relatively weak compared to ferromagnetic substances.
3. The domains in antiferromagnetic substances are oppositely oriented w.r.t. each other:
Antiferromagnetic substances have atoms with magnetic moments that naturally align themselves in opposite directions. This alignment causes the magnetic moments within the material to cancel each other out, resulting in no net magnetization. The domains in antiferromagnetic substances are regions where the atomic magnetic moments are aligned in the same direction. However, adjacent domains have opposite orientations, leading to a cancellation of their overall magnetic effects.
In summary:
- In diamagnetic substances, the magnetic moment is canceled due to the pairing of electrons.
- Paramagnetic substances are weakly attracted by a magnetic field due to the presence of unpaired electrons.
- Antiferromagnetic substances have oppositely oriented domains, resulting in no net magnetization.
- Due to the pairing of electrons, magnetic moment is cancelled
- Paramagnetic substances are weakly attracted by magnetic field
- The domains in antiferromagnetic substances are oppositely oriented w.r.t. each other
