question 14
which of the following is defined as a field that contains a unique value for each record?
a new field
b unique field
c primary key
d none of the above

Explanation:

A primary key is a field (or combination of fields) in a database table that uniquely identifies each record. A "New Field" has no such standard definition for uniqueness. A "Unique Field" is not the standard term used in database terminology for this specific concept. The standard term is "Primary Key".

Answer:

C. Primary Key
