Correct answer: C
A superkey is a set of one or more attributes that can uniquely identify a record in a database table. It may include extra attributes beyond what is necessary, but it ensures uniqueness. While a primary key is a minimal superkey (with no redundant attributes), the term 'superkey' is broader and directly matches the definition given in the question.
