An inductor of inductance $2 \, mH$ is connected to a $220 \, V, 50 \, Hz$ $AC$ source. Let the inductive reactance in the circuit be $X_1$. If a $220 \, V$ $DC$ source replaces the $AC$ source in the circuit,then the inductive reactance in the circuit is $X_2$. $X_1$ and $X_2$ respectively are:
- A$6.28 \, \Omega$,zero
- B$6.28 \, \Omega$,infinity
- C$0.628 \, \Omega$,zero
- D$0.628 \, \Omega$,infinity
