Final answer:
The set of attributes that closure can derive all the other attributes in the relation is a Super Key.
Step-by-step explanation:
In database management, the set of attributes that closure can derive all the other attributes in the relation is known as a Super Key. A super key is a combination of one or more attributes that uniquely identifies each record in a relation. It can be used to derive all the other attributes in a relation through functional dependencies.
For example, let's consider a relation called 'students' with attributes like student ID, name, and age. If the student ID is a super key, it can uniquely identify each student in the relation. By using the student ID, we can derive the name and age of the student.
So, the correct option is B. Super Key.
