By taking different slices through a cone you can create a circle, an ellipse, a parabola or a hyperbola .A conic section is the intersection of a plane and a cone .Conic section any curve produced by the intersection of a plane and a right circular cone. Depending on the angle of the plane
By changing the angle if intersection we can produce a circle, ellipse, parabola or hyperbola .
The CONIC SECTIONS get this name from the fact that they are formed by the intersection of a cone and a A) plane
Option A is the right answer.
