Which statement about AAC files emphasizes their quality versus size trade-off?

• A. AAC files are primarily used for bulk archival with tiny sizes.
• B. AAC offers low fidelity to keep sizes small.
• C. AAC is a format used mostly in gaming consoles for voice chat.
• D. AAC provides high-quality audio at the expense of larger file sizes.

Answer: (D)

The key idea is how audio quality and file size relate when using AAC. AAC compresses audio by discarding some data, so to achieve higher sound quality you need to retain more data, which makes the file larger. That trade-off—better quality requires more storage—is what the statement highlights. AAC is efficient and can deliver strong quality at reasonable sizes, but aiming for higher fidelity generally increases file size. The other options describe use cases or traits that don’t address this balance.
