ANSWER

When only switch A is closed, the circuit is open at 'B', hence the entire circuit would be open.

Zero bulbs would glow.

If only B is closed, only the first part of the three parallel bulb circuits would be open.

Hence 3 bulbs would glow (the one in series, and the two that are part of the closed circuit).

Hence option
