Which of the following is true of compasses? . a. a compass is a permanent magnet. b. compasses always point toward geographic south. c. a compass has only a north pole. d. compasses are not always magnetized

The correct answer is A. compass is a permanent magnet. 

Compasses were first made of Iodestone, a naturally magnetized ore of iron. So the correct answer will be that a compass is a permanent magnent. It couldn't point toward geographic south and it doesn't have only a north pole. I hope this answer helped you.
