Which intersection forms a parabola?

a) a plane intersects only one nappe of a double-napped cone, and the plane is parallel to the generating line of the cone.

b) a plane intersects only one nappe of a double-napped cone, and the plane is not parallel to the generating line of the cone.

c) a plane intersects both nappes of a double-napped cone, and the plane does not intersect the vertex.

d) a plane intersects only one nappe of a double-napped cone, and the plane is perpendicular to the axis of the cone.

A) A plane intersects only one nappe of a double-napped cone, and the plane is parallel to the generating line of the cone.

Step-by-step explanation:

A) Parabola

A plane intersects only one nappe of a double-napped cone, and the plane is parallel to the generating line of the cone.

The plane has to intersect with the base of the cone and forms a parabola.

B) Form Circle and hyperbola

C) Forms hyperbola  

D) Forms circle

Hope this will helpful.

Thank you.
