Solution:
As survey is made among 100 people. And it is also given that finding of each 100 person is presented to top nine resolution.
It means 100 people is mapped to 9 things, making 100 set of ordered pairs which we can represent points in two dimensional plane.
Since there are 9 things in the co-domain, it means each element of domain is related with one or more than one elements of co-domain.So, it will take time to represent these points on two dimensional plane and then to draw a line graph.
So, best way to represent these group of 100 people and their finding either through
1. Bar graph
but it will take more time to draw bars, so best way is
2. Pie chart
Option D: Pie chart,looks most beautiful choice from my point of view.
