The most important quality of lossless compression is best described by:

A. The data is transformed to usually make it smaller. It can always be reconstructed back to the original.

Lossless compression allows for the original data to be perfectly reconstructed from the compressed data without any loss of information. Therefore, the key aspect of lossless compression is the guarantee that the original data can always be recovered.
