Question

identify the cross section of the rectangular prism.
assume objects are perpendicular if they appear so.

Explanation:

A plane cutting through a rectangular prism at an angle that is not parallel to any face, but still intersecting four faces, will form a rectangular cross section. The plane shown intersects four faces of the rectangular prism, creating a 4-sided, right-angled shape. The other options (ring, oval, triangle) do not match the intersection of a plane with a rectangular prism in this orientation.
