In an \( \mathrm{AC} \) circuit the potential differences across an inductor and resistor joined in series are respectively \( 16 \mathrm{~V} \) and \( 20 \mathrm{~V} \). The total potential difference across the circuit is
(A) \( 20 \mathrm{~V} \)
(B) \( 25.6 \mathrm{~V} \)
(C) \( 31.9 \mathrm{~V} \)
(D) \( 53.5 \mathrm{~V} \)
