Solution

Verified by Toppr

Correct option is B. Antiferromagnetic
Solution:- (B) Antiferromagnetic
In the presence of the strong magnetic field, antiferromagnetic materials are weakly magnetised in the direction the field. This property of the materials is called antiferromagnetism and the materials which exhibit this propert are called antiferromagnetic materials.
