Which command is used to display the transparency grid?

The command used to display the transparency grid in Adobe Illustrator is found under the View menu and is labeled as "Show Transparency Grid." This grid is essential for designers as it provides visual feedback when working with transparent elements, making it easier to see how different colors and effects will appear against a transparent background.

When the transparency grid is activated, it typically displays a checkerboard pattern that indicates transparency. This feature is particularly useful when creating designs that incorporate transparency to ensure that the artwork looks as intended on various backgrounds. It can help identify areas of opacity in the artwork and verify that transparency effects are rendering correctly.

The other options do not serve this specific purpose. The Transparency options allow users to adjust quality settings, Grid settings pertains to the layout grid used for alignment and spacing, and the Transparency panel provides additional controls for managing the opacity and blending modes of objects but does not toggle the visibility of the transparency grid itself.
