A) 0.04 $\Omega$
B) 25 $\Omega$
C) 12 $\Omega$
D) 7.5 $\Omega$

The reactance of an inductor ($X_L$) is given by $X_L = \omega L$, where $\omega$ is the angular frequency in radians per second and $L$ is the inductance in henries. Substituting the given values, $X_L = 500 \times 0.05$ (since 50 mH = 0.05 H), we get $X_L = 25 \Omega$.
