Solution

The correct option is C $B_{1}$ dies out promptly but $B_{2}$ with some delay
Bulb $B_{1}$ dies out promptly, but $B_{2}$ dies out with some delay. This is because of the self-induced emf across L, causing the bulb $B_{2}$ to die out with some delay.

Figures represents two bulbs B1 and B2, resistor R and an inductor L. When the switch S is turned off :

The correct option is C B1 dies out promptly but B2 with some delayBulb B1 dies out promptly, but B2 dies out with some delay. This is because of the self-induced emf across L, causing the bulb B2 to die out with some delay.
