Tangent is drawn at any point (p ,q) on ...

Tangent is drawn at any point `(p ,q)` on the parabola `y^2=4a x` .Tangents are drawn from any point on this tangant to the circle `x^2+y^2=a^2` , such that the chords of contact pass through a fixed point `(r , s)`. Then `p ,q ,r` and`s` can hold the relation (A) `r^2q=4p^2s` (B) `r q^2=4p s^2` (C) `r q^2=-4p s^2` (D) `r^2q=-4p^2s`
