bar graph line graph pie chart data table
I gave my students this multiple choice question: Students studying the atmosphere want to display the percentage of each greenhouse gas as compared to the total amount of greenhouse gases found in the atmosphere. Which representation would be most appropriate for displaying these percentages?

Only one answer is correct among these 4 choices:
- bar graph
- line graph
- pie chart
- data table

Could you tell me which one is correct?
