The correct answer is C. Dodecahedron. A dodecahedron is a polyhedron with twelve flat faces, and in a regular dodecahedron, these faces are regular pentagons.

Here's a brief description of each option for clarity:

A. Octahedron: An octahedron has 8 faces, all of which are equilateral triangles.

B. Hexahedron: A hexahedron has 6 faces. The most common example is a cube, where all faces are squares.

C. Dodecahedron: A dodecahedron has 12 faces, all of which are regular pentagons in a regular dodecahedron.

D. Icosahedron: An icosahedron has 20 faces, all of which are equilateral triangles.
