Final Answer :
C
Explanation :
The most appropriate display for these data is a horizontal bar graph which is shown in display II. This is because the predicted values are categorical (countries) and the data is numerical (number of medals), making a bar graph the most appropriate choice. Display I is inappropriate because it shows data points on a two-dimensional scatterplot, which is not appropriate for this type of data. Display III is also inappropriate because it is a line graph, which is not appropriate for categorical data.
