Answer:
B. Similar squares
Step-by-step explanation:
The cross sections parallel to the base of a square pyramid, will form a square which will be similar to the base of the pyramid.
Also, if we consider a rectangular pyramid, the cross sections parallel to the base of the rectangular pyramid, will form a rectangle which will be similar to the base of the pyramid.
Thus, the paralel cross section to the base of any pyramid will form a similar shape of its base.
