Detailed Solution

When the switch is 'ON', all the bulbs A, B and C will glow at the same time.
When the switch is turned 'ON', current starts flowing in the circuit. This current is uniform and has the same value at all points in the circuit. This process of flowing of current happens instantaneously after the switch is 'ON'. Therefore, the same current flows in all the bulbs at the same time; hence, all the bulbs glow simultaneously.
