Solution
The correct option is A a line through P parallel to line l Steps to draw a line through O parallel to line AB––––––––––––––––––––––––––––––––––––––––––––––––––––––
Draw a transverse line through point O across line AB, at any angle
Draw an arcfrom the intersectionpoint of line AB and the transversal
Using the same radius, draw an arc at point O
Measure the distance between the points where the arc intersects line AB and the transversal
With the same length, draw an arc, centered at the intersection point of the earlier arc and ray
Draw a line through O and the intersection point of the two arcs.
Hence, the diagram in question, describes a line through P parallel to line l
