Identify a set of parallel and a set of perpendicular lines in this image.
An image shows that line BF intersects both line AD and line EH at 90 degree angles and that line CG intersects both line AD and line EH at 90 degree angles. At the points of intersections, a right angle symbol is shown, indicating that line BF is perpendicular to line AD and to line EH and line CG is perpendicular to line AD and line EH.
A) EH || CG, AD CG
B) AD || BF, EH CG
C) BF || CG, AD BF
D) AD || CG, EH BF
