A frequency polygon is best used when data are continuous, meaning they can take on any value within a range. A frequency polygon displays the distribution of continuous quantitative data with the use of lines connecting the midpoints of the tops of the bars in a histogram. On the other hand, a bar chart is best used when the data are discrete, meaning they can only take on specific values. A bar chart displays the distribution of categorical or discrete quantitative data with the use of bars of equal width. Therefore, the correct answer is B.
