Answer: D

Explanation:

zEDC is a compression acceleration capability, that enables you to do hardware-based data compression and decompression. It is designed for high-performance, low-latency compression, to reduce processor use, optimize the performance of compression-related tasks, improve disk usage, and optimize cross-platform exchange of data.

The compression format generated and used by zEDC Express is the Request for Comments (RFC) 1951 DEFLATE format, an industry standard that compresses data using the Lempel-Ziv 1977 (LZ77) and Huffman coding algorithms.
