Which of the following is the BEST option to make a complete point-in-time copy?

A snapshot is a point-in-time reference that captures the state and data of a virtual machine or volume at a specific moment, but it is not a complete, independent copy; it relies on the original disk for its base.

Synchronous replication continuously copies data changes from a primary storage system to a secondary system, ensuring data consistency but not creating a distinct point-in-time copy for independent use.

A clone creates a full, independent, and writable copy of a virtual disk, volume, or virtual machine at a specific point in time. Unlike a snapshot, a clone does not depend on the original object and can be used as a separate, fully functional instance.

A mirror creates an identical copy of data in real-time for redundancy, but it is not a distinct point-in-time copy for independent manipulation, as changes to the primary are immediately reflected on the mirror.
