If two lines lie on the same plane, then there are three possible relations between the two lines.
1) They are parallel
2) They are intersecting
3) They are coincident ( overlapping lines)
Only in the first case the lines do not intersect.
In the second case lie intersect at exactly one point.
In the third case, the lines intersect at infinite points as one line lies above the other line.
Hence PQ || RS and PQ & RS are coplanar.
A), C) , D) & E) are true statements.
