Which are prisms among the following?

A prism is a polyhedron that has two parallel congruent faces called bases. The other faces are parallelograms. To determine which shapes are prisms, one needs to examine the given shapes (which are not provided in the input data) and check if they meet this definition. Without the shapes, a specific solution cannot be given. For example, a rectangular prism has rectangular bases and rectangular lateral faces. A triangular prism has triangular bases and rectangular lateral faces.
