Answer : the correct option is, (b) series circuit
Explanation :
Parallel circuit : In this circuit, the potential across each of the components are same but the current flow in the circuit is equal to the sum of the current flow of each components.
Series circuit : In this circuit, the current flow each of the components are same but the potential across the circuit is equal to the sum of the potential of each components.
Open circuit : In this circuit, there will be no current flow that means the wires are cut off but in this circuit there will be some voltage.
Short circuit : When the live wire comes in the contact with the neutral wire, the short, this is the condition of the short circuit.
Hence, the given circuit is a type of of series circuit.
