Which tab is not available on left panel when you open a presentation?

Answer: Option C

When you open a presentation in PowerPoint, the left panel typically contains two tabs: the Outline tab and the Slides tab.

The Outline tab shows the text content of your slides, while the Slides tab shows thumbnail images of the slides.

The Notes tab is not available on the left panel; it is usually located below the slide area for adding speaker notes.

Therefore, the correct answer is that Notes are not available on the left panel.
