In an AC circuit, a resistance of \( \mathrm{R} \) ohm is connected in series with an inductance \( \mathrm{L} \). If phase angle between voltage and current be \( 45^{\circ} \), the value of inductive reactance will be.
(A) \( R / 4 \)
(B) \( R / 2 \)
(C) \( R \)
(D) cannot be found with the given data
