Lossless compression algorithms reduce file size without discarding any information, enabling exact restoration of the original data. Formats like ZIP and PNG use lossless methods in many cases. This is important for text and data files where accuracy is critical. Hence, the described technique is lossless compression.

Option A:
Option A is correct because lossless explicitly indicates that no information is lost during compression and decompression.

Option B:
Option B, lossy, compression permanently discards some data to achieve higher compression ratios and cannot perfectly reconstruct the original.

Option C:
Option C, hybrid, compression is not a standard name for this property and usually implies combining methods.

Option D:
Option D, destructive, is a vague term and not commonly used as a technical label in compression theory.
