1. which type of graph should be used for the data?

a) line b) circle

Explanation:

The data shows categorical groups (pizza types) and their corresponding vote counts, which represent frequencies of each category. A bar graph is standard for comparing frequencies of distinct categories. However, among the given options, a circle (pie) graph can also display the proportion of votes each pizza type received relative to the total votes. Wait, correction: Wait, no—wait, the options given are a) Line, b) Circle. Line graphs track trends over continuous data (like time), which this is not. Circle (pie) graphs show parts of a whole, which fits since votes are parts of the total class votes. Wait, but actually, bar graphs are ideal, but since that's not an option, circle is the correct choice from the given ones. Wait, no, let's recheck: The data is categorical with counts, so circle graph can represent the percentage each pizza has of total votes, while line graph is for sequential data.

Answer:

b) Circle
