Answer:
D) Square
Explanation:
We can start with the process of elimination.
Trapezoids don't have four right angles- can't be that. Neither do parallelograms.
So, we're just left with seeing whether rectangles have congruent sides- essentially, whether their sides are all the same shape or not.
Well, rectangles aren't always congruent. When you think of rectangle, usually, something with two long lines and two shorter lines comes to mind.
That leaves us with square.
