Quizplus · Accepted Answer

All three options (moving one end of a bar magnet through the coil, moving the coil toward one end of the bar magnet, and holding the coil near a second coil while the electric current in the second coil is increasing) can induce a current in a coil through electromagnetic induction. Therefore, the best choice is D, all of the above.
