D. Bar graph
Step-by-step explanation:
A bar graph is one of the types of graph or charts used to display statistical data. They are used to compare data between different groups. A bar graph makes use of either vertical or horizontal bars, which displays the actual data being compared.
Like other graphs, a bar graph contains a X-axis (horizontal), which contains the pizza toppings being compared and a Y-axis (vertical), which contains the number of people who chose each pizza. At the end, it will be easy to determine which pizza toppings is most popular from the bar graph because the pizza with the longest bar suggests the most popular.
