Answer 2

The correct answer is:

a rectangle

Explanation:

In a right pentagonal prism, the bases are pentagons and the lateral faces are rectangles.

If we take a cross-section perpendicular to the base, this same cross-section will be parallel to the lateral faces. This means it will be the same shape as the lateral faces, which is a rectangle.
