Lines AC and RS are
Coplanar
Parallel
Perpendicular
Skew

The correct option is Option D: Line AC and RS are skew lines.
A line is defined as set of points that extends infinitely in either direction. A line is the shortest distance between any two points.
Skew lines are two lines that never intersect and are not parallel also. Hence we can say that the two lines can not exist in the same plane.
From the figure it is clear that
Line AC and RS are in different planes and they are also not intersecting each other, hence according to the definition of skew lines, they are skew lines.
