Which statement describes WAV file limitations?

• A. They are widely used for streaming on the web.
• B. They have large file sizes and limited support on other platforms.
• C. They use lossless compression by default.
• D. They are primarily used for compressed music online.

Answer: (B)

WAV files usually store audio as uncompressed PCM data inside a RIFF container. Because there’s no compression, the file sizes are very large. That makes WAV great for editing and mastering when you need pristine quality, but it’s impractical for web streaming or distributing music where bandwidth and storage matter.

The statement about large file sizes and limited support on other platforms captures this limitation well: WAV isn’t efficient for streaming or online distribution, so formats that compress data (like MP3 or AAC) are preferred for those contexts. The other options mix up WAV’s properties—PCM is not a default lossless compression, and WAV isn’t primarily used for compressed music online.
