What is lossy compression commonly used for?

Answer and explanation

Correct answer: To greatly reduce the size of images, audio, or video

The governing concept is lossy compression: it removes some less noticeable or less important information so that a multimedia file occupies much less storage and transfers faster. The trade-off is that quality may decrease slightly. Therefore, option A is correct. Option B describes lossless preservation, while C concerns access control and D concerns installation, neither of which is compression.
