An inductor $L, a$ resistance $R$ and two identical bulbs $B_1$ and $B_2$ are connected to a battery through a switch $S$ as shown in the figure. The resistance of coil having inductance $L$ is also $R$. Which of the following statement gives the correct description of the happenings when the switch $S$ is closed?

A

The bulb $B_2$ lights up earlier than $B_1$ and finally both the bulbs shine equally bright.

B

$B_1$ light up earlier and finally both the bulbs acquire equal brightness.

C

$B_2$ lights up earlier and finally $B_1$ shines brighter than $B_2.$

D

$B_1$ and $B_2$ light up together with equal brightness all the time.
