Solution

The correct option is C cells of the battery will drain very quickly
When the circuit is closed, charges start flowing from one end to the other. While checking the LED, the circuit should not be closed for a long time. Otherwise, the cells of the battery will drain very quickly as this offers very little resistance to the flow of current.
