For two database tables to be linked, they must have at least one common attribute name. This common attribute is often referred to as a "key", which can be used to match records in one table with records in another table. This is the fundamental basis of relational databases, where data is organized into one or more tables (or "relations") of columns and rows, with a unique key identifying each row.

Composite keys, or keys that consist of two or more attributes, can also be used to link tables, but this is not a requirement. The same goes for having at least two tuples in the table - while this might make the table more useful, it's not a requirement for linking.

Finally, having the same data in all tuples is not a requirement for linking tables. In fact, having the same data in all tuples would make the table redundant and not very useful.

So, the correct answer is: At least one common attribute name.
