Answer:
B. bar graph
Explanation:
It would be best to use a "bar graph" if you would like to compare the different categories of data you've gathered. When the information in each data is independent from others, a bar graph is used. For example, in the situation above, every breakfast cereal has a different amount of sugar from another breakfast cereal. This kind of information is independent from another cereal and will never changed.
If one represents the information above in a bar graph, he can place the different breakfast cereals on the x-axis and place the sugar content on the y-axis. The higher the sugar content, the taller the bar will be while the lower the sugar content, the shorter the bar will be.
