Select the correct answer________ is the property that represents uniqueness.OptionsValueKeyIdAttribute

The correct answer is Attribute.

Explanation:

In the context of databases and data modeling, the term "attribute" refers to a property or characteristic of an entity. Specifically, an attribute is a field or column in a database table that can hold data pertaining to a particular aspect of that entity, thereby representing its unique characteristics. For example, in a student entity, attributes may include student ID, name, and enrollment date. Each attribute has a distinct value that helps uniquely identify each record in a dataset.

In contrast, "Value" generally refers to the data that an attribute holds, while "Key" pertains to identifiers used to access records in a database, such as primary keys. Among the given options, "Attribute" is most directly associated with the property of uniqueness when describing the characteristics of entities in a relational database.
