MP3 stands for Moving Picture Experts Group Layer-3 Audio. Which option corresponds to MP3?

• A. MP3
• B. MP4
• C. MAC
• D. MB

Answer: (A)

MP3 is an audio encoding format designed to shrink digital audio data while preserving listening quality, using perceptual coding to remove inaudible parts. It belongs to the MPEG family and is specifically MPEG Audio Layer III, which is why the term MP3 is used. MP3 files are audio-only, commonly with the .mp3 extension, and are widely used for music playback and streaming. MP4, in contrast, is a multimedia container that can hold video, audio, subtitles, and more, not an audio-only format. MAC refers to a computer operating system, not a media format. MB is a unit of data size (megabytes), not a file format. Since MP3 is the dedicated audio format described, it is the correct choice.
