What sequence creates a panel group by forming a free-floating panel and then adding another panel to it?

• A. Drag a panel off the dock to create a free-floating panel; then drag another panel’s tab into the new panel’s tab bar.
• B. Click the panel's minimize button twice.
• C. From the Window menu choose 'Panel Group'.
• D. Right-click a panel and select 'Join'.

Answer: (A)

Panel grouping comes from using drag-and-drop to combine panels, starting with a floating panel. First, you detach a panel from the dock to create a free-floating panel. Then you grab another panel and drag that panel’s tab into the free-floating panel’s tab bar. When you drop it, the second panel joins the floating one, forming a panel group that shares the same tab area and can be collapsed together. This two-step method is how you assemble related controls into a single, movable workspace unit. The other options don’t accomplish this: minimizing a panel hides it, a Window menu action doesn’t perform the two-panel assembly, and right-clicking a panel and choosing Join isn’t the sequence used to form a new panel group.
