Answer 1

Answer: C. A cross section parallel to the base of a right rectangular prism is congruent to the base.

Step-by-step explanation: Cross sections that are parallel to the base will give the shape of the base. That means that when you do a cross section that's parallel to the base, you're making a horizontal line that goes left to right that is the same as the base. Therefore, C is your answer.
