An inductor L, a resistanc eR 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 corrrect description of the happenings when the switch S is closed?

A

`B_(2)` lights 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 brightnesss,

C

`B_(2)` lights up earlier and finally `B_(1)` shines brighter than `B_(2)`

D

`B_(2)` lights up together with equal brightness all the time.
