Explanation:

• In MVC (Model - View - Controller), the Controller is responsible for handling user interactions. It receives user input, processes it, and updates the Model and View accordingly.
• In MVVM (Model - View - ViewModel), the ViewModel converts data from the Model into a format that the View can easily consume.
• In SwiftUI, the @State keyword is used for local state variables. It allows a view to have its own private state that can trigger a view update when changed.

Answer:

1. c. Controller
2. b. ViewModel
3. b. @State
