Solution

The correct option is D It contains unequal number of magnetic moment vectors in opposite direction
Ferrimagnetism arises due to the unequal magnetic moments in opposite direction, resulting net magnetic moment in one direction.

Magnetic moments of the domains are aligned in parallel and anti-parallel directions in unequal numbers
These materials are weakly attracted by magnetic fields as compared to ferromagnetic substances.

On heating, substance loses its ferrimagnetism property and becomes paramagnetic.

$F e_{3} O_{4}, ferrites like M g F e_{2} O_{4} and Z n F e_{2} O_{4}$ are examples of ferrimagnetism.
