Best answer
Correct answer is (a) Parent child relationship between the tables that connect them

To explain I would say: In a foreign key reference, a link is created between two tables when the column or columns that hold the primary key value for one table are referenced by the column or columns in another table. This column becomes a foreign key in the second table.
