The maximize button changes to the ____ button after you tap or click it.

A) Shut Down
B) Minimize
C) Restore Down
D) Close

When you click the maximize button, it maximizes the window to full size. When you click the button again or click the "Restore Down" button, the window is restored down to its previous size, hence the name "Restore Down." The "Minimize" button is a separate button that shrinks the window down to the taskbar or dock, and the "Shut Down" and "Close" buttons are unrelated to window management.
