In the circuit shown in the figure, when the switch is moved to the ’ON’ position,

$(a)$. the bulb A will glow first
$(b)$. the bulb B will glow first
$(c)$. the bulb C will glow first
$(d)$. all bulbs will glow together."

As soon as the switch is in the \'ON\' position, the current starts flowing in the entire circuit simultaneously. That is why all the three bulbs A, B, and C will glow together.

So, option $(d)$ is correct.
