In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel. Skew lines are on different planes.
Thus, Picture A represents skew lines.
Also, parallel lines are line that are always the same distance apart (equidistant), and will never meet.
Thus, Picture B represents parallel lines.
Lastly, parallel planes are planes in space that never intersect.
Thus, Picture C represents parallel planes
