B. Master Slide

Explanation

The slide that is used as a starting point for other slides in a presentation is called a Slide Master. The Slide Master defines the default layout and styles (such as fonts, colors, and placeholders) for the entire presentation. Any changes made to the Slide Master will be reflected in all the slides that use that master.
