Explanation:

In Microsoft PowerPoint, you can insert pictures and shapes into slides to enhance your presentations. However, there are certain views in PowerPoint where you cannot directly insert pictures and shapes. Let's explore these views and understand why the correct answer is option 'C' - Slide Sorter View.

Normal View:
Normal View is the default view in PowerPoint, which allows you to work on individual slides. In this view, you can insert pictures and shapes by selecting the "Insert" tab from the ribbon and choosing the desired option. Therefore, option 'A' is incorrect as you can insert pictures and shapes in Normal View.

Notes Page View:
Notes Page View is a PowerPoint view that allows you to see your slides along with the speaker notes. This view is mainly used for presenting, where you can have a reference of what to speak during each slide. Although you cannot directly insert pictures and shapes in this view, you can copy and paste them from other views like Normal View. Therefore, option 'B' is incorrect as you can insert pictures and shapes in Notes Page View indirectly.

Slide Sorter View:
Slide Sorter View is a view in PowerPoint that displays all the slides in a presentation as thumbnails on a single screen. It provides an overall view of the presentation and allows you to rearrange, delete, or duplicate slides easily. However, you cannot directly insert pictures and shapes in this view. To insert pictures and shapes, you need to switch to Normal View or another appropriate view. Therefore, option 'C' is correct as you cannot insert pictures and shapes in Slide Sorter View.

Summary:
In summary, you can insert pictures and shapes in Normal View and indirectly in Notes Page View by copying and pasting. However, you cannot insert pictures and shapes directly in Slide Sorter View. Therefore, the correct answer is option 'C' - Slide Sorter View.
