The answer is C.

Think of a pyramid. The base is a rectangle, and the four sides are triangles that meet at the top. If a plane were to intersect this rectangular pyramid perpendicular to the base and through the vertex, then the plane would intersect the pyramid vertically. The resulting cross section would be a trapezoid.
