Final answer:
The 'Notes Page' view is the correct answer, as it allows users to focus on one slide and corresponding notes at a time, which is ideal for editing presentation notes.
Step-by-step explanation:
The view that allows you to focus on one slide and one set of notes at a time in presentation software such as Microsoft PowerPoint is called Notes Page view. This view is distinct from the Slide Sorter view, which displays all slides in a grid so that you can see an overview of your presentation, or the Normal view, which typically shows the slide, the thumbnails of other slides, and an area for notes.
Notes Page view is particularly useful when you are polishing your speech or presentation notes for each individual slide. It displays a single slide and its associated speaker notes in full, providing a convenient way to review and edit your notes in preparation for your presentation.
