Answer:
3) Dims in, Brightens out
Explanation:
The relationship between the inductance of a coil and the current is inverse.
As the rod is thrusted into the solenoid, the inductance increases, which in turn decreases the current and the bulb gets dimmer. This is also because some magnetic force is drawn away from the solenoid and the battery.
When the rod is removed, the inductance of the solenoid decreases, the current increases, and the bulb becomes brighter.
