Solution
The correct option is C 3
Steps for drawing a line parallel to a given line:
Step 1: Mark a point A on the line PQ and a point R not lying on the line PQ.
Step 2: Join A and R.
Step 3: Draw an arc with A as centre and mark its intersecting points on PQ and AR as C and D respectively..
Step 4: Draw an arc with R as centre and mark its intersecting point on AR as B.
Step 5: Take measure of CD by compass. Draw an arc with B as centre and mark its intersecting point with the arc drawn in step 4 as E.
Step 6: Join the points E and R and extend it, we get aline parallel to PQ.
Number of arcs drawn = 3

Take any point R not on it. Through R, draw a perpendicular to
