Which of the following options is correct?

The correct choice indicates that Client Actions can call Server Actions, which is a fundamental aspect of the OutSystems architecture.

In OutSystems, Client Actions are designed to run on the user's device, processing data and interacting with the user interface without requiring a round trip to the server. Server Actions, on the other hand, execute on the server-side, where they can manipulate the database, perform complex calculations, and handle secure transactions.

The ability for Client Actions to call Server Actions is crucial in building responsive applications because it enables the app to gather and send data to the server seamlessly, facilitating interactions that require server-side processing.

When a Client Action calls a Server Action, it typically does so through an HTTP request, which minimizes latency and enhances the user experience by allowing operations like data retrieval or updates to be done in the background. This mechanism maintains a clear separation of responsibilities between client-side and server-side logic, which is a cornerstone of modern web architecture.

In contrast, the other options do not correctly align with how the OutSystems framework operates. For instance, Screen Actions are limited to their specific screens and cannot directly invoke actions on other screens; Client Actions cannot directly call other Client Actions and are not meant to communicate directly with them in a way that
