In the following question find out the alternative which will replace the question mark?

Poles : Magnet :: ? : Battery

Terminals 

The answer is Terminals.

The analogy is between the poles of a magnet and the terminals of a battery. The poles of a magnet are the points where the magnetic field is strongest, and the terminals of a battery are the points where the electrical current flows in and out of the battery. So, the missing word must be the points where the electrical current flows in and out of a battery. Of the answer choices, only terminals fits this description.

The other answer choices do not fit the analogy. Cells are the individual units that make up a battery, power is the energy that is produced by a battery, energy is the capacity to do work, and Fiji is a country. None of these are the points where the electrical current flows in and out of a battery.
