Which PNG format supports unlimited colors and lossless compression?

Explanation:
The key idea is color depth and lossless compression in PNG formats. PNG-8 uses a limited palette of up to 256 colors, which restricts the range of colors you can represent. PNG-24 stores color as 8 bits for red, green, and blue per pixel, giving about 16.7 million possible colors—far more colors than a palette-based format—while still using lossless compression. This combination means you get very rich, smooth color representation without any degradation in quality. The other options either rely on a small palette (GIF and PNG-8) or aren’t PNG variants (TIFF). So PNG-24 is the format that best matches “unlimited colors” with lossless compression.
