a. rectangular prism
b. triangular prism
c. cylinder
d. cone
e. square pyramid
f. triangular pyramid

Answer with explanation:

When these shapes are cut perpendicular to base,the following have  rectangular cross sections:

A. Rectangular Prism→Rectangular prism , has base in the form of rectangle,so when cut perpendicular to base,the base as well as other faces, will be in the shape of Rectangle.

B. Square Pyramid:→Square pyramid has base in the shape of Square,so when cut perpendicular to base,the base  will be similar to Square .

As,Every Square is a Rectangle,so the Square Pyramid when cut perpendicular to base ,the base Resembles with rectangle.

C: Triangular Prism: When triangular prism ,cut perpendicular to base,one of the face will resemble with Rectangle.

Option A :   Rectangular prism

Option B: Triangular Prism

Option E : Square Pyramid
