Solution

The correct options are
A $F e_{2} O_{3}$
C $C r O_{2}$
Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets or are attracted to magnets and the materials are called ferromagnetic materials.

$F e_{2} O_{3}$ is ferromagnetic. $F e_{3} O_{4}$ is ferrimagnetic.

$C r_{2} O_{3}$ is antiferromagnetic. $C r O_{2}$ is ferromagnetic.

Option A and D are correct.
