The bar graph below displays students’ responses to the question "What caffeinated drinks do you consume?”

A bar graph titled Caffeinated Drinks has drink on the x-axis and relative frequency on the y-axis. Coffee, 0.8; tea, 0.7; soda, 0.7; energy, 0.2.

Would it be appropriate to display the data with a pie chart?

Yes, because the data are grouped into categories.
Yes, because the data can be represented by a relative frequency compared to the whole.
No, because the data add up to more than 100%.
No, because the data categories are too broad.
