In a pie chart, which element helps explain what each color or slice represents?

• A. Legend
• B. Data labels
• C. Chart title
• D. Axis

Answer: (A)

In a pie chart, the legend is the element that ties each color to its corresponding category, so you can tell what each slice represents just by its color. The legend sits beside the chart and shows a color swatch with the category name, making interpretation quick and clean, especially when there are many slices. Data labels can show the value or percentage of a slice, but they don’t identify what the color stands for. The chart title describes the overall subject, and an axis isn’t used for pie charts, so they don’t help with color-to-category mapping.
