An Alternate Key is any candidate key that is not selected as the primary key of the table. Candidate keys are attributes (or combinations of attributes) that uniquely identify a row in a table. Among these, one is chosen as the primary key, while others are considered alternate keys. For example, in a table of students, both StudentID and Email might uniquely identify records. If StudentID is the primary key, Email becomes an alternate key. Alternate keys are useful for additional indexing or as foreign keys in related tables. Why Other Options Are Incorrect :
