__ is a set of one or more attributes taken collectively to uniquely identify a record.

Breakdown of the options:

Super key: Any set of attributes that uniquely identifies a tuple (row) in a relation (table).

Candidate key: A minimal super key (no unnecessary attributes).

Primary key: A chosen candidate key to uniquely identify a record.

Foreign key: A field in one table that refers to the primary key in another table.

So, while a super key is a broader term encompassing any set of attributes that uniquely identify a record, it's not the most specific or commonly used term. Candidate key or primary key would be more appropriate in most cases.
