Which file formats are used for audio?

• A. PDF
• B. WAV/MP3
• C. XML
• D. ASCII

Answer: (B)

The concept here is recognizing which file formats are designed to store audio data. Different file types are built for different kinds of information; PDFs are for documents, XML is for structured data, and ASCII is plain text. Among the options, WAV and MP3 are the ones used for audio. WAV is an uncompressed audio format that stores raw sound data, which is common in editing and production because it preserves quality. MP3 is a widely used compressed audio format that lowers file size by removing inaudible parts of the sound, making it great for distribution and playback on devices with limited storage or bandwidth. Together, they cover both uncompressed and compressed forms of audio storage, which is why they’re the correct choice.
