Answer:
D
Step-by-step explanation:
A is not correct. A trapezoid does not have 4 equal sides.
B is not correct. Same reason as A even if the trapezoid is isosceles.
C is not correct. A square has 4 equal sides and 2 sets of parallel lines and 1 right angle. That is not what this figure looks like.
D is the correct answer.
E is incorrect. A rectangle has 2 pairs of equal sides and two sets of opposite sides that are equal and parallel. It also has at least 1 right angle.
The original figure has none of these things.
