Which steps are required to export a PowerPoint presentation as a PDF?

To export a PowerPoint presentation as a PDF, the correct procedure involves navigating through the 'File' tab, where you select 'Export' and then choose 'Create PDF/XPS'. This method is specifically designed for creating PDF files and ensures that all slides, formatting, and any embedded media are preserved in the exported document.

Using the 'Export' option is pivotal because it consolidates the necessary settings for converting the presentation into a PDF format effectively. This process is straightforward and intuitive for users, making it the primary choice for exporting documents.

While other options may suggest printing or sending through different methods, they either do not relate directly to creating a PDF from PowerPoint or involve steps that are not intended for this specific task. The approach outlined in the correct answer is tailored to ensure that the PDF reflects the presentation accurately, maintaining the integrity of visual and text elements as designed in PowerPoint.
