Well, there are 4 options given, and according to seeing the graph, if you take a close look, the numbers on the x axis is not arranged equally, this might cause a huge fault in the calculation and marking of the graph, and plus you are supposed to give one unit gap between the numbers on the y axis since your skipping the few numbers in between. Overall I would precisely say that the graph is uneven and the numbers aren't having proper gaps in between, which cause significant error. After your done making your graph in a way proper way, consider the 2nd option, since recalculation and marking needs to be done after all.
