Figure shows two bulbs and
resistor
and an inductor
When the switch
is turned off,
both die out promptly
both die out with some delay
dies out promptly but

dies out promptly but
with some delay
Here the bulb will die out promptly but
with some delay. The reason is that the branch of bulb
contains inductance. Due to the effect in inductance, the current in this branch continues to flow for sometime even the switch
is turned off.
