Answer: GH
Step-by-step explanation:
In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel to each other,
Or we can say two lines which are not parallel and are not lie on the same plane.
Thus, by the above definition,
In the given diagram, The skew lines of BD are EF, GH, CG, AE and EG,
⇒ First option is correct.
