Answer:
Line 3
Step-by-step explanation:
Observe each line and keep in mind all points.
Line 1 is wrong because it goes over each and every point.
Line 2 is wrong because it ignores the leftmost point and rightmost point.
Line 4 is wrong because it goes under each and every point.
This leaves Line 3 as good by default. It goes over as many points as it goes under and doesn't ignore any points.
