Show Answer
Correct Answer: D

To retrieve a data value from a relational database as described by E.F. Codd, the necessary pieces of information are the attribute (which specifies the type of data), the relation name (which specifies the table), and the primary key (which uniquely identifies the row). These components together allow for precise access to a specific data value within the database.
