Q. The adjoining figure shows two bulbs $B_{1}$ and $B_{2}$, resistor $R$ and an inductor $L$. When the switch $S$ is turned off
A) Both $B_{1}$ and $B_{2}$ die out promptly
B) Both $B_{1}$ and $B_{2}$ die out with some delay
C) $B_{1}$ dies out promptly but $B_{2}$ with some delay
D) $B_{2}$ dies out promptly but $B_{1}$ with some delay
Explanation
