The value of current in two series LCR circuits at resonance is same. Then

• A

  both circuits must be having same value of capacitance and inductance

• B

  in both circuits ratio of L and C will be same

• C

  for both the circuits $X_L$/$X_C$ must be same at that fre­quency

• D

  both circuits must have same impedance at all frequen­cies
