Final answer:
A self-contained program belongs to the Model-View-Controller (MVC) architectural pattern.
Step-by-step explanation:
The MVC pattern is commonly used in software development to separate the presentation, logic, and data layers of an application. In the MVC model, a self-contained program acts as the controller component, which handles user input, interacts with the model (data), and updates the view (user interface).
For example, in a web application, the self-contained program would receive user requests, process them, and update the underlying data or render a response to be displayed in the user's browser.
