Which statement correctly describes handling transparency in web-graphic formats?

• A. PNG supports transparency and lossless compression.
• B. JPEG supports transparency and is best for sharp text.
• C. SVG cannot handle transparency.
• D. GIF is the only format with transparency.

Answer: (A)

Transparency is handled best when the format includes an alpha channel so each pixel can be partially transparent. PNG does this and uses lossless compression, which preserves edge sharpness and detail while keeping transparency intact. That combination is why PNG is ideal for graphics with transparent backgrounds, logos, and images that need crisp edges. JPEG, on the other hand, uses lossy compression and does not support transparency, so it isn’t suitable for images that require transparent areas or clean text edges. SVG can handle transparency through opacity in vector shapes, so it also supports transparent rendering, not limited to bitmap formats. GIF offers transparency but only binary transparency with a restricted color palette, which limits quality for detailed images.
