The SQL statement provided will produce:

d. Customer data rows so that there are no duplicate names

Explanation:

The SQL statement is using the DISTINCT keyword, which is used to return only distinct (different) values. In a table, a column may contain many duplicate values; and sometimes you only want to list the different (distinct) values.

The SQL SELECT DISTINCT statement is used to return only distinct (different) values. In this case, it's applied to the lname (last name), fname (first name), and dob (date of birth) columns in the customer table.

This means the output will be a list of customers, but any row where the lname, fname, and dob are the same as another row will be excluded. So, it will return customer data rows so that there are no duplicate names (assuming the combination of lname, fname, and dob makes a name unique).
