In a relational database, which one of the following is CORRECT:

Solution

A prime attribute is one that is part of a candidate key.
In BCNF (Boyce-Codd Normal Form), for every functional dependency $X \to Y$, $X$ must be a super key.
If all attributes are prime, there cannot exist a dependency where a non-superkey determines another attribute.
Hence, the relation is automatically in BCNF.
