This question tests knowledge of common file extensions associated with Microsoft Office applications. File extensions are suffixes added to the end of a file name, typically after a dot, which indicate the file's format or type. This helps the operating system determine which program should open the file.
The correct answer is ppt. The .ppt extension stands for PowerPoint Presentation and was the standard file format for Microsoft PowerPoint presentations prior to Office 2007. While newer versions primarily use .pptx, .ppt remains a valid and recognized extension for PowerPoint files, especially for compatibility with older software versions.
