Answer:
We will obtain a rectangle on slicing this rectangular prism parallel to it's base.
Hence, option 1) is true.
RECTANGLE.
Step-by-step explanation:
On slicing this geometrical figure; which is a rectangular prism parallel to it's base then we will obtain a figure similar to it's base of the same dimensions as it's base.
As the base of the rectangular prism is a rectangle so on slicing this 3-dimensional figure parallel to it's base we will obtain rectangles.
Hence, option 1 is true.
RECTANGLE.
Let 
be the side of the triangle and 
be the side of the square.
Let 
be the perimeter of the triangle and 
be the perimeter of the square.
We have the following relationship:
Which finally implies
