A circle of radius r passes through origin and cut the y-axis

Question

A circle of radius r passes through origin and cut the y-axis at $P$ and $Q$ . The locus of foot of perpendicular drawn from origin upon line joining the points $P$ and $Q$ is (A) $(x^{2} + y^{2})^{3} = r^{2} (x^{2} y^{2})$ (B) $(x^{2} + y^{2})^{2} (x + y) = r^{2} (x y)$ (C) $(x^{2} + y^{2})^{2} = r^{2} (x^{2} y^{2})$ (D) $(x^{2} + y^{2})^{3} = 4 r^{2} (x^{2} y^{2})$
