Final answer:
The B. notes pane is the location where you can add notes to each slide in a presentation. These notes won't appear on the slides during the presentation but can be seen in the Presenter View.
Step-by-step explanation:
The location where notes can be added in a presentation software like Microsoft PowerPoint is the notes pane. The notes pane is typically found at the bottom of the window when you're in the 'Normal' view. It allows you to type speaker notes for each slide, which can be very helpful during a presentation. The notes you add here won't appear on the slides themselves during the presentation, but you can view them on your screen as you present if you're using the Presenter View. On the other hand, the notes master is used to customize the appearance of your speaker notes, not to add the notes themselves.
The correct answer is B. notes pane.
The notes pane is the location where notes can be added to a PowerPoint presentation. This is a separate pane within the PowerPoint interface that allows users to add speaker notes or additional information related to each slide.
The presenter pane is used to view the presentation while presenting, the slide pane displays the slides themselves, and the notes master is used to modify the appearance of the notes pages.
