A statement which is true about the metal boxes pictured below is that: C. the magnetic force will be strongest on box #1.
The law of magnetism states that the like poles of a magnet would repel one another while unlike (different) poles attract each other. This ultimately implies that, two north (N) poles of a magnet would repel one another while a north (N) and south (S) would attract each other.
In this context, we can infer and logically deduce that the magnetic force in both the north (N) and south (S) poles of a magnet are equal in force but this magnetic force is weak at the middle portion of the magnet bar.
Based on the law of magnetism, a statement which is true about the metal boxes pictured below is that the magnetic force will be strongest on box #1 because it is nearest to the magnet.
