Selected Answer: B
Not A - Creates a dependency on Salesforce as the central identifier and limiting flexibility. Not C - Adds complexity and increases data management overhead. Not D - Unnecessary complication if a suitable identifier already exists in the MDM solution. B - Leverages the MDM as the master source, adds flexibility and it's easy to implement.

Selected Answer: B
B, because the external Id should align to the Id in the MDM solution. The MDM solution is meant for being the source of truth. Not A because Salesforce IDs should never be hard coded, even as an external Id. Not C, a custom object to store a customer Id offers no benefits for data matching records so that the MDM can maintain the record. Not D, a MDM solution was already stated exists.
