Final answer:
In a Pega application, the correct pairing for a data element is a Property and its Value. This is a basic concept in the Pega system, which is essential for building enterprise applications.
Step-by-step explanation:
In a Pega application, each data element is a pairing of a Property and its corresponding Value. This means that the correct answer to the question is b) Property and Value. Properties in Pega are analogous to fields in a database table, where each property holds a piece of data or a value. For example, a property could be 'CustomerName' and the value could be 'John Doe'. This is a foundational concept in Pega, which is a platform used for developing enterprise-level applications.
