Answer
Correct option: A.
Lamp will not glow
a
(a) When a lamp is connected to $D.C.$ line with a capacitor. If will form an open circuit. Hence, the lamp will not glow.

Assertion : Between any two given energy levels, the number of absorption transitions is always less than the number of emission transitions.
Reason : Absorption transitions start from the lowest energy level only and may end at any higher energy level. But emission transitions may start from any higher energy level and end at any energy level below it.
