Answer: (C)

Verified step by step guidance

1. Understand the purpose of the graph: We want to display percents of a whole, which means showing parts of a total in relation to each other.
2. Recall that a scatterplot is used to show relationships between two numerical variables, not parts of a whole.
3. Recognize that a boxplot summarizes the distribution of a numerical variable, showing median, quartiles, and potential outliers, but does not display parts of a whole.
4. Know that a histogram displays the frequency distribution of numerical data by grouping data into bins, which is useful for showing the shape of data but not percentages of a whole.
5. Identify that a pie chart is specifically designed to show proportions or percentages of a whole by dividing a circle into slices representing each category's share.
