A cone is cut by a plane parallel to the slant height of the cone. What is the shape of the cross section that is formed?

A plane parallel to the cone's slant height cuts a cone. The resulting cross-section has a U shape. Option B is correct.
It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.
A plane parallel to the cone's slant height cuts a cone. A U-shaped figure results from cutting a cone along a plane parallel to the cone's slant height.
Hence, option B is correct.
