Tableau Desktop Foundations Practice Question

Placing a discrete dimension on the Color shelf tells Tableau to encode each distinct member of that dimension with its own categorical hue. Because the view already has a single bar per region, Tableau stacks the marks inside each bar-one colored segment for every customer segment-and automatically adds a color legend. Continuous palettes are only used when the field on Color is a measure or a continuous dimension, and Color can always accept dimensions, so the other options are incorrect.
