Explanation

Option B is correct because the statement contains an inaccuracy in how it describes DRS. Huawei Cloud DRS does support real-time migration, backup migration, real-time synchronization, data subscription, and real-time disaster recovery, but it does not describe its function as supporting "data circulation between multiple data sources" - that phrasing does not correspond to an official DRS capability or use case. DRS is purpose-built for one-directional or structured replication workflows between source and target databases, not general data circulation across multiple sources simultaneously.

Option A is wrong because accepting the statement as true would require "data circulation between multiple data sources" to be a recognized DRS function, which it is not according to the official service definition.

Memory tip: Remember the five core DRS capabilities as two migration types (real-time, backup) plus three ongoing operations (synchronization, subscription, disaster recovery) - if a question adds a sixth capability like "data circulation," treat it as a red flag that the statement is false.
