The data needs to be matched within source system and all data must be retained. There is a field present in the data which identifies the source system. Which approach would best accomplish this task?

  A. Pass all the data into a Match Unduplicate stage blocking on the Source System field.
  B. Pass all the data into a Remove Duplicates stage and process the remaining data into an Unduplicate match blocking on the Source System field
