Identify the third step from the first four steps which describe constructing a parallel line through a point.
A) Set compasses' width to the distance where the lower arc crosses the two lines.
B) Without adjusting the compasses' width, move the compasses to R and draw an arc.
C) Draw a transverse line through R and across the line PQ at an angle, forming the point J where it intersects the line PQ.
D) With the compasses' width set to about half the distance between R and J, place the point on J, and draw an arc across both lines.
