Option 1: rectangle.

Reason: a plane parallel to the rectangular base cuts each of the four triangular lateral faces in a line segment parallel to the corresponding base edge, so the intersection is a four-sided figure with opposite sides parallel and proportional to the base — i.e., a rectangle (degenerating to a point if the plane passes through the apex).
