In the context of visualizing quantitative data, which of the following chart types can be used to plot one or more data series on a secondary axis?

Answer: (B)

Verified step by step guidance

1. Understand the purpose of a secondary axis: It is used when you want to plot two or more data series that have different scales or units on the same chart, allowing easier comparison.
2. Review each chart type's characteristics: A histogram displays frequency distribution of a single variable, a box plot summarizes data distribution with quartiles, and a pie chart shows proportions of a whole.
3. Recognize that a combo chart (combination of bar and line charts) allows plotting multiple data series with different scales by assigning one series to the primary axis and another to the secondary axis.
4. Identify that histograms, box plots, and pie charts do not support secondary axes because they are designed for single data series or specific types of summaries.
5. Conclude that the combo chart is the appropriate choice for plotting one or more data series on a secondary axis due to its flexibility in handling multiple scales.
