Detailed Solution & Explanation
A multiple axis line chart (also called a dual-axis line chart) is used in statistical data presentation to plot more than one time series on the same graph when the variables have different units of measurement or vary significantly in scale. If the variables had the same units and similar scales, they could be plotted on a single y-axis. When the units of the variables are different (for example, plotting temperature in Celsius and rainfall in millimeters over time) and there is more than one time series, using multiple axes ensures that each series is scaled appropriately and can be analyzed simultaneously without distortion. Thus, both conditions must be met. Hence, **Option D** is the correct answer.
