Which of the following section does not exist in a slide layout?

Slide layouts contain formatting, positioning, and placeholder boxes for all of the content that appears on a slide. Placeholders are the dotted-line containers on slide layouts that hold such content as titles, body text, tables, charts, SmartArt graphics, pictures, clip art, videos, and sounds. Slide layouts also contain the colors, fonts, effects, and the background (collectively known as the theme) of a slide.
