Explanation:

A circle graph (pie chart) is used to show the proportion or relative size of different data categories within a whole. "Demonstrates how data changes over time" is for line graphs. "Shows the frequency of data points" is for histograms or frequency tables. "Provides exact numerical data" is not the main use of a circle graph (it shows proportions, not exact numbers). So the correct option is the one about showing relative size of data categories.

Answer:

Shows the relative size of data categories
