Which file type is commonly associated with video files?

• A. JPEG
• B. MP4 (MPEG-4)
• C. DOCX
• D. PDF

Answer: (B)

The choice of MP4 (MPEG-4) as the correct answer is supported by its widespread use as a video file format. MP4 is a digital multimedia container format that is utilized for storing video and audio, as well as other data such as subtitles and still images. It is highly efficient in compressing video files while maintaining a reasonable quality, which makes it a popular choice for streaming and sharing video content online. JPEG is primarily an image format, commonly used for photographs and graphics, and is not suitable for video. DOCX is a file format associated with word processing documents created in Microsoft Word, and PDF is a format used for presenting documents in a manner independent of application software, hardware, and operating systems, primarily for text and images, rather than video. Thus, MP4 stands out clearly as the format specifically designed for video files.
