In the given relation Dataset(DatasetID, DatasetName, Source, CollectionDate, Domain, OwnerName, OwnerEmail, UpdateFrequency), the most appropriate primary key is DatasetID. This attribute uniquely identifies each dataset in the relation and ensures entity integrity. Since DatasetID is assumed to be unique for every dataset record, it can function as a minimal and stable identifier, making it suitable as the primary key. Meaningful functional dependencies can be derived based on the semantics of the attributes. The primary functional dependency is: DatasetID →
