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.
Answer: It's B
