At the customer service counter, there are three steps to process a product-return by a customer. These steps are: 1) examine the original sales invoice to ensure the customer purchased the item from the store, 2) enter the item back into the store's inventory records, and 3) issue the customer a store credit for the amount of the item. An analysis of the last 2,000 customer return transactions uncovered 30 errors. This results in a DPMO of approximately:
A. 200
B. 5,000
C. 8,333
D. 15,500
E. 20,750
