Name the segments that are skew to AB.I have attached an image with the diagram and answers.

Choice A is eliminated since GH is parallel to AB. The segment GH is NOT skew to AB.

Choice B is also eliminated since CD is parallel to AB

Choice C is eliminated because AC intersects AB at point A. Skew lines never cross and they are not parallel in 3D space.

Choice D is the only thing left. The segments EG, DH, CG and FH are all skew to AB. They aren't parallel to AB and they never cross AB

So choice D is the final answer
