By arranging a stem-and-leaf display for each group side-by-side, it is easy to compare the distributions of scores for the two groups. It allows for quick visual comparison of the central tendency and variability of each group's scores. Option B would not allow for comparison between the two groups as the scores would be mixed together. Option C may be confusing and hard to read. So, option A is the best choice in this case.
