$A$ circuit of negligible resistance has an inductor of $0.16 H$ and a capacitor of $25 \mu F$ connected in series with an alternating voltage source. The resonant frequency of the circuit is:

  • A
    $\frac{150}{\pi} Hz$
  • B
    $\frac{200}{\pi} Hz$
  • C
    $\frac{250}{\pi} Hz$
  • D
    $\frac{400}{\pi} Hz$
