The correct answer is A. PDF stands for Portable Document Format, which is a file format used to present and exchange documents reliably, independent of software, hardware, or operating system. It is often used for sharing documents, such as e-books, forms, manuals, and presentations, that are intended to be viewed and printed consistently across different devices and platforms. PDF files can be created, viewed, and edited with different software applications, including Adobe Acrobat, Microsoft Word, and Google Docs.
