The correct answer is D. A presentation design template.
A presentation design template is a pre-made set of slides that includes the slide layout, fonts, colors, and other design elements. Using a presentation design template can save you time and effort, and it can help you create a consistent look and feel for your presentation.
To use a presentation design template, open PowerPoint and click on the “Design” tab. In the “Themes” group, click on the “New Theme” button. In the “Themes” dialog box, select the template that you want to use and click on the “Apply” button.
The slide layout option allows you to change the layout of a slide. The add a slide option allows you to add a new slide to your presentation. Outline view allows you to see the text of your presentation in an outline format.
I hope this helps!
