An alternating current of frequency \( f \) is flowing in a circuit containing a resistor of resistance \( R \) and a choke of inductance \( L \) in series. The impedance of this circuit is:
(A) \( \mathrm{R}+2 \pi f \pi \mathrm{L} \)
(B) \( \sqrt{R^{2}+L^{2}} \)
(C) \( \sqrt{R^{2}+2 \pi f L} \)
(D) \( \sqrt{R^{2}+4 \pi^{2} f^{2} L^{2}} \)
