CodeIgniter is loosely based on which of the following development patterns?
- A.
  
  Model-view-viewmodel
- B.
  
  Model-view-presenter
- C.
  
  Model–view–controller
- D.
  
  Presentation-abstraction-control
Correct Answer
C. Model–view–controller

Explanation
CodeIgniter is based on the Model–view–controller (MVC) development pattern. This pattern separates the application logic into three interconnected components: the model, the view, and the controller. The model represents the data and business logic, the view handles the presentation of the data to the user, and the controller manages the communication between the model and the view. This pattern helps in organizing the codebase, improving code reusability, and enhancing maintainability of the application.

Additionally, Codeigniter allows for easy extension through the use of libraries, helpers, class extensions, and system hooks. It also requires nearly zero configuration, making it easy to set up and start using. Finally, Codeigniter is free to use and is an open-source framework, meaning it can be used and modified by anyone.

  Post_controller_constructor
- B.
  
  Display_override
- C.

C. Pre_override

Explanation
The answer is "Pre_override" because it is not a valid hook point in Codeigniter. The other three options (post_controller_constructor, display_override, and Post_system) are valid hook points that can be used in Codeigniter for executing custom code at specific points during the application's execution. However, "Pre_override" is not a recognized hook point in Codeigniter.
