B. triangle
When making a perpendicular slice to a right rectangular pyramid that goes from the base through the apex, the resulting two-dimensional figure will be a triangle. This is because the slice will go through the apex and two opposite corners of the rectangular base, forming a triangle with three sides and three vertices.
