Answer:
The light grows dimmer when the meter is deflected to left.
Option B
Explanation:
When the light grows brighter, that means the resistance of the system has decreased. The resistance decreases when the meter is deflated to right. So, the light grows brighter when the meter is deflected to right.
When the light grows dimmer, that means the resistance of the system has increased. The resistance increases when the meter is deflated to left.
