Selecting a primary key that uniquely identifies each line in the table ensures that there are no repeating groups in the table. This is because the primary key uniquely identifies each record in the table, and hence there can be no repetition of data. Removing duplicated records or creating foreign keys may address some issues related to data duplication, but it may not entirely eliminate repeating groups. Creating another table and transferring duplicated instances into the new table also addresses the issue of data duplication but is not necessary to eliminate repeating groups.
