a. a neutral object.
b. nonmagnetic.
c. a permanent magnet.
d. a temporary magnet.

Answer;

C. a permanent magnet.

A ferromagnetic material that has domains that remain aligned for a long period of time is called a permanent magnet.

Explanation;Permanent magnets are either ferromagnetic or ferrimagnetic materials. Ferromagnetic materials such as iron, nickel and steel have a large, positive susceptibility to magnetic fields. These materials are strongly attracted to magnetic fields and are capable of retaining their magnetic properties after the removal of the external field.Ferromagnetic materials attain strong magnetic properties since they have magnetic domains. When these materials are fully magnetized the domains are aligned  to produce strong magnetic field resulting to formation of permanent magnets.
