Each page on the clipboard is an _____ of a specific class.

The correct answer is "Instance" because in the context of Pega, each page on the clipboard represents a specific instance of a class. In Pega's object-oriented structure, a class is a blueprint for data, and an instance is a realization or specific representation of that class.

When you create a page in Pega, you are creating an instance of a particular class that contains properties and values defined by that class. This instance holds specific data that can be manipulated during the execution of a case or process. For example, if you have a class for Customer, each page on the clipboard may represent a different customer instance, containing unique data for that particular customer such as their name, contact information, and any other relevant details.

The other options do not accurately capture this concept. An object could generally refer to any entity in programming, but does not specifically imply an individual instantiation of a class. An element may refer to parts within a structure, but does not convey the idea of a concrete instance. A component might suggest parts of a whole in a system architecture but again fails to denote the concept of instances within an object-oriented framework. Therefore, "Instance" is the most precise term to describe each page on the clipboard as it directly relates
