What action must be taken first to insert an audio file from the Documents folder in PowerPoint?

To insert an audio file from the Documents folder in PowerPoint, opening the backstage view and selecting the Info button is a critical initial step. This approach is necessary to access various options related to your presentation, including file management tasks.

Within backstage view, you can navigate to different sections where you can manage your files effectively, though the more direct method for inserting audio would actually involve using the Insert tab where media options are located. The process of inserting involves identifying the correct location of the audio file first, which is why navigating through backstage first can ensure you've selected the right file path. From there, you would typically then proceed to the Insert tab to further access the audio options directly.

The other options provided may represent steps or features in PowerPoint, but they do not serve as the first necessary action for inserting an audio file specifically. By beginning with backstage view, you set up an organized approach to file management before performing the actual insert operation.
