The correct answer is: B. From Insert Menu choose Duplicate Slide
Option A is incorrect because pressing Ctrl+A will select all of the text on the slide, not the slide itself. Option C is incorrect because redoing everything on a new slide is not the most efficient way to create a copy of a slide. Option D is incorrect because it is not a valid option.
To duplicate a slide in PowerPoint, follow these steps:
