Answer
- C Duplicate for the nearly identical rows
- D Useful for the customer number
Explanation
The useful constraint tests that an attribute contains some repeated values, because an attribute with only unique values like an ID usually provides no learnable patterns. The duplicate constraint finds identical or near identical values or instances and limits how many are allowed, often zero.
