Solution

Antiferromagnetism, type of magnetism in solids in which adjacent ions that behave as tiny magnets

Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field.

MnO- Antiferromagnetism
O2- Paramagnetism
NaCl- Diamagnetism
Fe3O4- Ferrimagnetism

Hence, the correct answer is option: 'D'.
