The table "customer-sales" is most likely to have a concatenated key because it represents a many-to-many relation between the "customer" and "sales" tables. This means that there can be multiple rows with the same customer ID and sales ID, but different other attributes like date or quantity. Therefore, a concatenated key consisting of both the customer ID and the sales ID would be required to uniquely identify each row in the table.
