3D Scan - Icosahedron

Geometry Level pending

A 3D scan is taken of an icosahedron.

To do this, a plane starts at one face and is slowly lowered until it gets to the opposite face, always staying parallel to those two faces.

As it is lowered, the cross section takes on a variety of polygons with different numbers of edges.

Which of the following shows this progression, i.e. the number of edges the cross section has, as it is lowered? (Starting and ending with 3, representing the triangular faces it starts/finishes on)
