The solid with one circular face, one curved surface and one vertex is known as:
(a) cone
(b) sphere
(c) cylinder
(d) prism

We know that

A cone is a three dimensional solid geometric shape having a circular base and a pointed edge at the top called the apex.

A cone has one face and a vertex.

There are no edges for a cone.

Therefore, the solid with one circular face, one curved surface and one vertex is a cone.
