C. generalized audit software to search for address field duplications.

Since the name is not the same (due to name variations), one method to detect duplications would be to compare other common fields, such as addresses. Subsequent review to determine common customer names at these addresses could then be conducted. Searching for duplicate account numbers would not likely find duplications, since customers would most likely have different account numbers for each variation. Test data would not be useful to detect the extent of any data characteristic, but simply to determine how the data were processed.
