The correct answer is Super key.

Here's why:

1. A super key is a set of one or more keys that can be used to identify a record uniquely in a relation.

2. In other words, a super key is a set of attributes within a table that can uniquely identify each record within a table.

3. Therefore, a super key is a superset of all keys in a relation.

4. The other options, Sub key, Candidate key, and Foreign key, do not fit the definition of a superset of all keys in a relation.

So, the correct answer is Super key.
