$A$ coil having an inductance of $\frac{1}{\pi} \text{ H}$ is connected in series with a resistance of $300 \text{ } \Omega$. If $20 \text{ V}$ from a $200 \text{ Hz}$ source are impressed across the combination,the value of the phase angle between the voltage and the current is

• A
  $\tan^{-1}\left(\frac{5}{4}\right)$
• B
  $\tan^{-1}\left(\frac{4}{5}\right)$
• C
  $\tan^{-1}\left(\frac{3}{4}\right)$
• D
  $\tan^{-1}\left(\frac{4}{3}\right)$
