    Answer (B) Magnetite Magnetite is an ore mineral of Iron, with the chemical formula Fe3O4. Magnetite is one of the major oxides of iron, and is ferrimagnetic i.e., it is attracted to a magnet and can be easily magnetized to become a permanent magnet itself. Magnetite is the most magnetic of all the naturally-occurring minerals on Earth. Fe-pyrite is relatively less magnetic and hence the most accurate answer should be magnetite.
