B) duplicated
C) synchronous
D) asynchronous
E) versioning

Asynchronous approach allows for some delay in updating the replicated data, which means retrieved data may not be up-to-the-minute accurate. This approach can be used when the nature of the distributed replicated data and applications that use it can tolerate this delay. Choices A and B refer to keeping exact copies of data, which may not be feasible in all distributed systems. Synchronous approach (Choice C) requires that all updates be made immediately and simultaneously across all replicas, which can create latency issues and increase the risk of inconsistencies. Versioning approach (Choice E) is not related to updating replicated data.
