The three elements users can add to a pie chart are a chart title, a(n) _____________, and data labels.

• A. Legend
• B. Axis
• C. Gridlines
• D. Data Series

Answer: (A)

A chart that shows parts of a whole uses a legend to identify what each colored slice represents, making it easy to map each category to its portion without cluttering the chart itself. The chart title explains what the chart is about, and data labels can show exact values or percentages on the slices. Axes and gridlines don’t apply to pie charts because there are no axes to plot against, and a data series isn’t an added display element in this context. So the missing element that fits with a chart title and data labels is the legend, which explains the colors of the slices.
