In which Service Studio layer can Screens and Blocks be found?

Screens and Blocks are fundamental elements of the user interface within the OutSystems platform, and they are located in the Interface layer of Service Studio. This layer is specifically designed for building the visual components of applications, where developers create the layout, design, and navigation of the user interface components that users interact with.

In the Interface layer, developers can create and manage reusable UI components (Blocks) and define the structure of different screens, ensuring consistency and efficiency in the design process. This separation of concerns allows developers to focus on the visual presentation in this specific layer, while other layers in Service Studio manage different aspects of the application, such as business logic and data management.

Thus, the correct answer highlights the designated layer where all user-facing aspects are implemented, reinforcing the structure and organization of an OutSystems application.
