This is called an ellipse.
The general answer is an ellipse.
Ellipse. (sources) internet class.
An ellipse which, when the plane is perpendicular to the axis of the cone, becomes a circle.
When a right circular cone is intersected by a plane that passes through its vertex and touches the edge of each nappe, the resulting shape is a triangle. This triangle is formed by the intersection line extending from the vertex to the edges of the cone's surfaces, effectively creating a triangular cross-section of the cone.

The general answer is an ellipse.
An ellipse is produced.
The "conic section" that is produced when you slice a cone with a plane that passes through only one nappe of the cone but that is not parallel to an edge of the cone is known as an ellipse. In the case where the plane is perpendicular to the axis of the cone, the ellipse becomes a circle.

If I understand your description correctly, a line.
A parabola.
