Answer: (A)

HyperClone uses a copy-on-write approach to create a writable clone, so you can start reading and writing to the target LUN immediately without waiting for a full data copy.

When the clone is created, it doesn't duplicate all data. The clone and the original LUN share the same data blocks, with a mapping that allows both to be used right away. If you write to the clone (or the source), the system copies the original blocks as needed and writes the new data to separate blocks. This preserves data isolation while enabling instant access, and the actual copying happens in the background only for blocks that diverge due to writes.
