Consider a curve \( a x^{2}+2 h x y+b y^{2}=1 \) and a point \( P \) not on the curve. A line is drawn from the point \( P \) intersects the curve at points \( Q \& R \). If the product \( P Q . P R \) is independent of the slope of the line, then the curve is
(a) Parallal lines
(b) A line
(c) A circle
(d) Perpendicular lines
