What is the shape of the cross-section formed when a cone intersects a plane as shown in the drawing?

Answer:
Option (B) is correct.
A triangle is formed when the cone intersect the given plane.
Step-by-step explanation:
Given an image in which a cone is drawn and a surface parallel to y-axis is given.
We have to find what is the shape of the cross section form when the cone intersect the plane.
Consider the plane since, the given plane is parallel to y axis and parallel to cone also.
So when we intersect the cone along y- axis a shape is formed.
Since triangle of cone is parallel to y-axis. So, triangle is formed.
Option (B) is correct.
Thus, A triangle is formed when the cone intersect the given plane.
