  2. A voltage source and a conductor.
  3. A power source and a bulb.
  4. A voltage source and a conductor.

Correct Answer: B

Explanation:

We know that, V = IR ⇒ I = V / R. So, any conductor would have their own resistance, because of its resistivity. While a voltage source is applied in this conductor, according to the above expression an electric current flows through the circuit.
