A completed step is shown by which UI element?

• A. Filled green circle
• B. Empty circle
• C. Red square
• D. Blue triangle

Answer: (A)

Progress indicators use fill and color to convey status. A completed step is typically shown as a filled shape, often green, which signals success and that this part of the process is done. An empty circle usually means the step hasn’t been completed yet or is currently in progress, so it wouldn’t indicate completion. The red square and blue triangle aren’t standard cues for a finished state, so they don’t communicate completion as clearly. Because the filled green circle clearly and universally signals that the step is finished, it’s the best choice to represent a completed step.
