In PowerPoint, which option can be used to apply the same design to all slides?

In PowerPoint, the Design tab is used to apply the same design, including themes, colors, fonts, and background styles, to all slides in a presentation. This ensures a consistent visual appearance throughout your slideshow.

• The Transition tab is used to add visual effects that occur when moving from one slide to the next.
• The Animation tab is used to add motion effects to individual objects (text, images) on a slide.
• "Template tab" is not a standard tab in PowerPoint; templates are typically accessed through the File menu or applied via the Design tab.
