Best answer
Correct choice is (c) PbZrO3

For explanation: In the given list: NiO and V2O3 are antiferromagnetic substances, Fe3O4 is Ferrimagnetic and PbZrO3 is antiferroelectric. Antiferroelectric materials are those materials having ions which can polarize without external field (spontaneous polarization).
