Which three of these file types work well with HTTP compression? (Choose three.)

MP4 video files use codecs such as H.264 or H.265 that already apply heavy perceptual compression, leaving virtually no redundancy for HTTP compression to exploit while adding CPU cost.

Digital photos in JPEG or PNG format are already encoded with lossy or lossless compression algorithms, so applying HTTP compression yields negligible reduction and wastes processing resources.

Plain text files consist of highly repetitive character sequences that gzip and deflate algorithms can compress by 60-80%, making them ideal candidates for HTTP compression.

Static HTML pages are text-based and contain repetitive markup tags, whitespace, and inline content that respond extremely well to compression algorithms like gzip.

CD-quality audio in formats like WAV contains binary pulse-code modulation data with low textual redundancy, and compressed formats like MP3 have already eliminated the redundancy that compression targets.

Modern Word documents (.docx) use an XML-based Open Packaging format internally, meaning their content is largely text with repetitive structure that compresses effectively.
