Final answer:
An 3) Instance is created automatically to register an entry id when a new object is instantiated from a class in object-oriented programming.
Step-by-step explanation:
The object type created automatically to register an entry id is an Instance. When you create a new object in programming, specifically in object-oriented programming languages, an instance of a class is automatically generated. This instance is the actual object that holds the specified properties and behaviors defined by its class. For example, if you have a class named Book, when you create a new Book object, you are creating an instance of the Book class, and this instance will have its own unique entry id or reference in memory.
The object type that is automatically created to register entry ID is an instance. An instance is a specific occurrence or realization of a class. In object-oriented programming, a class serves as a blueprint for creating instances or objects.
When a class is defined, it is used to create objects or instances. Each instance represents a unique occurrence of that class and has its own set of characteristics, known as instance variables or properties, which store data specific to that instance.
In the context of registerring an entry ID, an instance can be created automatically by calling the class constructor or by invoking a relevant method that handles the registration process.
