Key Points

WAV vs MP3 Format:

• WAV (Waveform Audio File Format) is an uncompressed, lossless audio format developed by Microsoft and IBM. It preserves all the original audio data, making it ideal for professional recordings and editing.
• MP3 (MPEG-1 Audio Layer III) is a compressed, lossy format, meaning it reduces file size by discarding some audio data, which may lead to slight loss in quality.

Benefits of using WAV over MP3:

• (A) The size of the audio file is larger – ✅ WAV files are significantly larger because they are uncompressed.
• (B) The audio quality is better – ✅ WAV offers higher fidelity due to lossless compression, making it superior for professional use.
• (C) There are no cross-platform issues – ❌ While WAV is widely supported, it may not be as universally supported across all mobile and web platforms as MP3.
• (D) Audio file is uncompressed and lossless – ✅ This is the main feature of WAV format, making it ideal for editing and archival.

Therefore:

Correct statements: (A), (B), and (D)

Incorrect statement: (C) — MP3 has better cross-platform compatibility than WAV.

Hence, the correct answer is: option 4) (A), (B) and (D) Only.
