Which term describes the text to accompany charts for accessibility?

• A. Alternative
• B. Caption
• C. Description
• D. Metadata

Answer: (A)

In accessibility, non-text content like charts needs a text alternative that describes the content so someone using a screen reader can understand it. This is called alternative text, or alt text. It serves as the concise replacement for the image’s meaning when the chart can’t be seen. For charts, alt text should capture the essential data and the main takeaway, with a longer description available if more detail is needed. A caption is helpful for sighted users to label or describe the chart visually, but it isn’t the primary accessibility mechanism. A description can provide more detail, but the standard term specifically used for accessibility is alternative text. Metadata describes information about the data itself, not the user-facing description of the chart.
