b. Choose the correct answer below. A. A circle graph is more appropriate when the data is categorical. B. A circle graph is more appropriate when the data can be considered as part of a whole. C. A circle graph is more appropriate when the data cannot be considered as part of a whole. D. A circle graph is more appropriate when the data is continuous.

To determine the correct answer regarding the appropriateness of a circle graph (also known as a pie chart), let's analyze each option: A. A circle graph is more appropriate when the data is categorical. - This statement is partially true, as circle graphs can represent categorical data, but it doesn't capture the full essence of when they are most useful. B. A circle graph is more appropriate when the data can be considered as part of a whole. - This statement is accurate. Circle graphs are designed to show how different parts contribute to a whole, making them ideal for representing data that can be divided into categories that sum up to a total. C. A circle graph is more appropriate when the data cannot be considered as part of a whole. - This statement is incorrect. Circle graphs are not suitable for data that cannot be represented as parts of a whole. D. A circle graph is more appropriate when the data is continuous. - This statement is also incorrect. Circle graphs are not typically used for continuous data, which is better represented by line graphs or histograms. Based on this analysis, the correct answer is: **B. A circle graph is more appropriate when the data can be considered as part of a whole.**
