A. Line graph
B. Pie chart
C. Flow chart
D. Bar graph

Answer 1

Answer: Bar graph

Explanation:

You would use a bar graph because the researcher is using categorial data so the best way to present this type of data are bar graph, pie charts and frequency tables. We wouldn't use a pie chart here because we are not comparing multiple things so a bar graph would be the best visual presentation.

Hope this helps:)
