The correct statement in defining Model in Model-View-Controller Architecture is: "Model is responsible for maintaining data."

The Model in MVC architecture is the part of the system that handles the logic for the application data. It responds to requests for information, responds to instructions to change its state, and even to instructions to notify observers in event-driven systems.

The other statements are incorrect because:

- "Model presents the data in a particular format." This is incorrect because presenting data is the responsibility of the View in MVC architecture.
- "Model performs the business operation that modify the state of the data." This is partially correct. While the Model does handle data and its state, it doesn't perform business operations. Those are typically handled by the Controller.
- "Model is responsible for displaying all or a portion of the data." This is incorrect because displaying data is the responsibility of the View in MVC architecture.
