Suppose the parabola $(y-k)^2 = 4a(x-h)$ has vertex $A$ and passes through $O = (0,0)$ and $L = (0,2)$. Let $D$ be an end point of the latus rectum. Let the $Y$-axis intersect the axis of the parabola at $P$. Then,$\angle PDA$ is equal to

  • A
    $\tan^{-1} \frac{1}{19}$
  • B
    $\tan^{-1} \frac{2}{19}$
  • C
    $\tan^{-1} \frac{4}{19}$
  • D
    $\tan^{-1} \frac{8}{19}$
