Alt text gives screen readers a summary of the bar chart's data
Short answer
B Alt text carries the chart's data summary to screen reader users.
Question
Key Takeaways
Alt text is the property screen readers announce for a visual — writing a sales-by-country summary there makes the chart's data available to non-visual users.
A bar chart showing sales by country must expose a summary of its data to screen reader users, so the visual property that carries descriptive text must be configured.
Common mistake: Reaching for tab order or layer order — both govern navigation and stacking for sighted keyboard users; neither conveys any information about the chart's data.
Expert Analysis
Why the Answer Is Correct
When a screen reader user focuses a visual, it announces the visual's alternative text, which is authored in the visual's format pane under General > Alt text. Writing a summary of the sales-by-country data there (B) is exactly how Microsoft documents making chart content accessible, delivering the data summary through the screen reader.
Why the Other Options Are Wrong
Conditional formatting (A) changes how cells and bars are colored by value — a visual encoding that screen readers do not narrate as a summary. Tab order (C) sequences which visual receives keyboard focus next, controlling navigation rather than content description. Layer order (D) decides overlap rendering between visuals; no text is involved.
