Correct answer: B
The PNG file format specification explicitly defines the use of the DEFLATE compression algorithm for compressing image data streams. While Huffman coding is a component within Deflate, the standard identifier for the algorithm used in PNGs is specifically Deflate. LZW compression is primarily associated with GIF files rather than PNG images.
