Answer(A) a frustum of a cone

Solution

            Cone – A cone is a three dimensional geometrical shape that tapers smoothly from a flat base to a point called the apex or vertex.

 

            Frustum of a cone – It is portion of a solid that lies between one or two parallel planes cutting it

            Cylinder – A cylinder is a three dimensional solid that has two parallel based joined by a curved surface at a fixed distance.

            Sphere – The set of all points in three dimensional space lying the same distance from a given point.

            Thus A cone which is cut through a plane parallel to its base and then the cone that is formed one side of that plane is removed then the new part which is formed is called frustum of a cone.
