Answer :
c . They both have a circular base is the similarity between the cone and the cylinder.
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called an apex or vertex. A cone is formed by a series of line segments, half-lines, or lines connecting vertices that are common to all points on the base in a plane that does not contain vertices.
Cylinders are traditionally three-dimensional solids and are one of the most basic curved geometric shapes. In elementary geometry, it is considered a prism with a circle as its base.
