Which of the following is an audio file extension?

• A. .exe
• B. .mp3
• C. .zip
• D. .txt

Answer: (B)

The choice of .mp3 as an audio file extension is correct because it is one of the most widely used formats for compressing audio files, allowing for efficient storage and playback of music and sound on digital devices. The .mp3 format supports a significant reduction in file size while maintaining a reasonably high quality of sound, making it ideal for both streaming and downloading audio content. In contrast, the other file extensions serve different purposes: .exe is typically used for executable files, which are applications that can run on a computer; .zip is a compressed file format used for packaging multiple files into one archive, often to save space or for easier transfer; and .txt is a text file used for storing plain text without any formatting. These distinctions highlight why .mp3 is specifically associated with audio content.
