What do you click to display the format background task pane?

To display the format background task pane in PowerPoint, you click the Design tab in the Customize group. This is because the Design tab is specifically geared towards altering the overall appearance and layout of your slides, including background settings. Within this tab, you have access to various options that allow you to customize slide backgrounds, including solid colors, gradients, patterns, or images.

When you select the Design tab, the option labeled "Format Background" becomes available, which opens the task pane for background formatting options. This task pane allows users to make changes such as filling the background with colors or images, setting transparency levels, and applying designs uniformly across multiple slides, thereby enhancing the visual appeal of the presentation.

The other choices involve different tabs and functionalities that do not lead to the background formatting options. For instance, the View tab is generally used for adjusting how the slides are displayed or organized rather than for styling or formatting them. The Format tab in Picture Tools pertains specifically to modifying images within your slides and would not be relevant for changing the slide background. Similarly, the Home tab focuses on basic editing functions like text formatting and does not include background customization.
