Detailed Solution

The above statement is False.
The divergence of magnetic field lines indicates the increase in the strength of the magnetic field near the ends of a current-carrying solenoid is a false statement.
A solenoid is a coil that consists of a large number of circular turns of insulated copper wire. As the distance from the current-carrying solenoid increases the magnetic field at the ends of the solenoid appears to diverge. Hence, as the distance from the solenoid increases magnetic field strength decreases.
The correct statement would be, the divergence of magnetic field lines indicates the decrease in the strength of the magnetic field near the ends of a current-carrying solenoid.
