Solution

The correct option is A
A frustum of a cone

Explanation for the correct answer:
When a cone is divided into two parts by a plane through any point on its axis parallel to its base, then the upper and lower parts obtained are cone and a frustum respectively.
The figure given below depicts how the shapes are formed when a cone is cut into two parts on its axis parallel to its base.

Hence, option A is correct.
