Foreign Key is a non-key attribute, whose values are derived from the primary key of some other table. Explanation: • Primary Key - It is used to uniquely identify the tuples in a relation. • Foreign Key - It is used to represent the relationship between two tables/relations and its value is derived from the primary key of some other table. • Candidate Key - refers to the set of all attributes which can uniquely identify records in a relation. • Alternate Key - It is a candidate key that has not been selected to be the primary key. So, the correct answer is Foreign Key.
