In an LR circuit, the value of \( L \) is \( \left(\frac{0.4}{\pi}\right) \) and the value of \( R \) is \( 30 \Omega \). If in the circuit, an alternating emf of \( 200 \mathrm{~V} \) at \( 50 \mathrm{cps} \) is connected, the impedance of the circuit and current will be:
(A) \( 50 \Omega, 4 \mathrm{~A} \)
(B) \( 40.4 \Omega, 5 \mathrm{~A} \)
(C) \( 30.7 \Omega, 6.5 \mathrm{~A} \)
(D) \( 11.4 \Omega, 17.5 \mathrm{~A} \)
