Preeti is trying to draw a line parallel to PQ through a point R (not on PQ). How many arcs will she need to draw and how many times she needs to change the distance between the compass tip and the pencil tip respectively?

The correct option is C 3 and 1
Steps for drawing a line parallel to a given line:
Step 1: Mark a point A, not on the line 'l'.
Step 2: Mark point B on line 'l'.
Step 3: Draw line segment joining points A and B.
Step 4: Draw an arc with B as the centre, such that it intersects line 'l' at D and AB at E.
Step 5: Draw another arc with the same radius and A as the centre, such that it intersects AB at F.
Step 6: Draw another arc with F as the centre and distance DE as the radius.
Step 7: Mark the point of intersections of this arc and the previous arc as G.
Step 8: Draw line 'm' passing through points A and G.
No. of arcs drawn = 3
No. of times the distance between compass tip and pencip tip is changed = 1
