Answer:
Explanation:
When looking at this figure, it wants you to look at the parallel lines. Those little marks that looks like >, indicate that those two lines are parallel. So, then you look at your answers. A. is saying that lines AB and AC are parallel, well AC does not even have a >, so it is not parallel with anything. B. says that AC and BD are parallel. Well, that cannot be true because none of those lines have a >. C. says that AD and BC are parallel, which looks true, but they do not have a > to signify that they are parallel. D. is saying that AB and CD are parallel. They both have the >, so that means that they must be parallel.
The answer is D.
