Choice "B" is correct. Translation software is a required component in an EDI environment, and it represents an additional cost not incurred in the traditional paper environment.
Choice "c" is incorrect. Redundant data checks to verify that transactions are not recorded twice may be used in an EDI environment (especially if a VAN is used), but they are not specifically required.
Choices "a" and "d" are incorrect. In an EDI environment, communication between trading partners is automated. Because the receiving company no longer has to manually input transaction data into its own internal computer system, data entry labor and the potential for errors are both reduced.
