The correct answer is: A. Show Comparisons
The figure shows a bar graph that compares the number of people who have used different types of social media in the past year. The graph is well-designed and easy to read. It shows the data clearly and accurately, and it includes a title, axis labels, and a legend.
However, the graph does not show any comparisons between the different types of social media. For example, it does not show how the number of people who use Facebook compares to the number of people who use Twitter. This makes it difficult to understand the relative popularity of the different types of social media.
To show comparisons, the graph could include a line graph that shows the trend in the number of people who use each type of social media over time. This would allow users to see how the popularity of each type of social media has changed over time.
Alternatively, the graph could include a pie chart that shows the percentage of people who use each type of social media. This would allow users to see how the different types of social media are used by different groups of people.
Overall, the figure is well-designed and easy to read. However, it would be more informative if it showed comparisons between the different types of social media.
