Quizplus · Accepted Answer

A foreign key is a column or set of columns in a relational database table that provides a link between data in two tables. It refers to a primary key which is present in another table, hence providing a relationship between the two tables. The other options, namely discrete, relational, and variable, are not directly related to this concept of foreign keys in databases.
