Solution
The correct option is A all in series
Components connected in series are connected along a single path, so the same current flows through all of the components. The current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component. In a series circuit, every device must function for the circuit to be complete. One bulb burning out in a series circuit breaks the circuit. A circuit composed solely of components connected in series is known as a series circuit.
In this case, the 3 bulb are connected in a single path except that a battery is connected across the first bulb.
Hence, all the 3 bulbs are connected in series.
