An important element of database design that ensures that the attributes in a table depend only on
the primary key is:

A.
Data reuse.

B.
Data integrity.

C.
Data normalization.

D.
Database management.

Explanation:
The correct answer is “Data normalization”. Normalization includes eliminating redundant data and
eliminating attributes in a table that are not dependent on the primary key of that table. In answer
a, a database management system (DBMS) provides access to the database and is used for
maintaining the database. Answers “Data integrity” and “Data reuse” are distracters.
