None of them.
You may have neglected to copy something else that goes with the question, as there are no "above lines".
PERPENDICULAR

|_ example of a perpendicular line is shown above:
Magnetic field lines are usually depicted as curved lines extending away from the source. They are neither parallel or perpendicular (though they appear more parallel than perpendicular).
It is C which has no perpendicular or parallel lines
The addition sign is formed by two intersecting lines, as is the cross. The two lines are perpendicular to each other.
= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.
Perpendicular lines intersect.

PERPENDICULAR
Lines that intersect at 90 degrees are perpendicular lines
