Which file formats does Narrate offer for export?

The correct answer indicates that Narrate offers the export file formats of dva, png, pptx, and pdf. These formats are commonly used for various purposes such as visual presentation and documentation, which aligns with the capabilities of many narration and multimedia tools.

The 'dva' format is specific to certain applications related to audio narration, allowing for optimized multimedia content. The inclusion of 'png' as a graphics file format facilitates high-quality image export, while 'pptx' caters to users looking for integration with Microsoft PowerPoint for presentations. Finally, 'pdf' is universally recognized for document sharing, maintaining formatting across different platforms.

The other proposed formats in the options are less relevant or not primarily associated with narration or multimedia export, which contributes to why they do not fit with the capabilities of Narrate as effectively as the correct answer.
