Second option.

Explanation:

The following answer is false because foreign keys establish connections across relationships, these values should become the subset of their equivalent primary key values as well as should have that identical data type as the primary key.

It is a specific or set of columns in such a database table that offers a connection among the information in both tables. This serves like the cross-reference through tables as it corresponds to a primary key of an other table, thus forming a relation among them.
