NEET 2020 Physics question on Electromagnetic Induction and AC

A series LCR circuit is connected to an ac voltage source. When L is removed from the circuit, the phase difference between current and voltage is π3\dfrac{\pi}{3}. If instead C is removed from the circuit, the phase difference is again π3\dfrac{\pi}{3} between current and voltage. The power factor of the circuit is :
  1. A.
    0.5
  2. B.
    1.0
  3. C.
    –1.0
  4. D.
    zero
