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.
