Best answer
The correct answer is (b) Paramagnetic

The best I can explain: The properties of a Ferro-magnet are depended on temperature. When they are heated up to a high temperature, it loses its Ferro magnetic properties and become a paramagnet. This transition occurs at a specific temperature, called the transition point.
