Let \( \mathrm{A} \) and \( \mathrm{B} \) be two distinct point on the parabola \( \mathrm{y}^{2}=4 \mathrm{x} \). If the axis of the parabola touches a circle of radius \( r \) having \( \mathrm{AB} \) as its diameter, then the slope of the line joining \( \mathrm{A} \) and \( \mathrm{B} \) can be -
W
(A) \( \frac{-1}{\mathrm{r}} \)
(B) \( \frac{1}{r} \)
(C) \( \frac{2}{r} \)
(D) \( \frac{-2}{\mathrm{r}} y \)
in:
\( -y \)
