Your answer choices are cut off. Only A and B are showing. Both A and B are true, so they are not the answer. A is true because the midsegment is always half that of the parallel side. Choice B is true because of similar triangles leads to congruent corresponding angles which means the sides are parallel.
The answer is either C or D. Choice C seems to show up but only partially. Choice D seems to be completely left out for some reason. Please repost with the answer choices.
