Which UI element shows which windows are currently open?

• A. Help bar
• B. Task bar
• C. Tool tip
• D. Status bar

Answer: (B)

The taskbar is the UI element that shows which windows are currently open. It sits along the edge of the screen and lists an icon for each open window or running application. The active window is usually highlighted, and you can switch to any other window with a click, giving you a quick at-a-glance view of all open items and easy navigation between them. Why the other options don’t fit: a status bar is inside a window and displays information about the current document or state of that window, not a list of open windows; a tool tip is a small popup that appears when you hover over a control to describe it; a help bar, when present, provides access to help topics rather than listing open windows.
