Answer: D
Correct answer: A named subset of slides from the presentation, shown as a separate sequence
A Custom Show is a named selection of slides from a presentation, played in an order you define, without the slides being deleted or reordered in the file itself. It solves a practical problem: the same deck must be given as a ten-minute overview to one audience and a forty-minute account to another. Rather than keeping two files that drift apart, one file holds every slide and two custom shows draw on it. It is created from the Slide Show tab under Custom Slide Show, and a show can be started from there or linked to with a hyperlink - which allows a menu slide offering several routes through the same material. A slide may appear in several custom shows, and its content is stored once. The related tools serve different purposes: Hide Slide skips individual slides in the main sequence, and Sections group slides for editing rather than for presenting.
