Answer 1

The correct option is C Domain

The values for an attribute or a column are drawn from a set of values known as a domain.

In data management a data domain refers to all the values which a data element may contain. The rule for determining the domain boundary may be as simple as a data type with an enumerated list of values.

An attribute is a characteristic. In a database management system (DBMS), an attribute refers to a database component, such as a table. It also may refer to a database field. Attributes describe the instances in the row of a database.
