cylinder
An upright pentagonal prism has two congruent parallel bases and 15 edges.
a cylinder has two faces that are circles
This is a general description of an oblique prism. Use the link to learn more.
That would be some kind of prism. To answer the question more specifically, I would need to know the shape of the bases.

A cylinder would fit such a description of it.
Both a cylinder and a prism can have parallel and congruent bases.

It is a cylinder
An upright pentagonal prism has two congruent parallel bases and 15 edges.
Cylinder - a solid figure formed by two congruent parallel circles joined by a curved surface.
A cylinder would fit the given description
A sphere is.
A cylinder
It could be a prism, but need not be. A regular dodecahedron, for example, is not a prism but has parallel and congruent pentagonal bases. You can also have any antiprism (see link).
Prism!
A solid with congruent ends and parallel sides is typically called a prism. More specifically: 🔷 Types of Solids with Congruent Ends and Parallel Sides Prism: A solid with two congruent, parallel polygonal bases and sides that are parallelograms. Examples include: Rectangular prism (like a box) Triangular prism (like a tent shape) Pentagonal prism, etc. Cylinder: A special case where the congruent ends are circles, and the side is a curved surface. It also fits the definition of having congruent ends and parallel sides. So depending on the shape of the ends (polygonal or circular), the solid could be a prism or a cylinder.
