Final answer:

The correct answer is option c) 1 and 4 only. In the Model-View-Controller (MVC) architecture, the 'V' stands for 'View'. The Views are responsible for user interface (UI) representation.

Step-by-step explanation:

The correct answer to which components the 'V' in MVC is responsible for is '1 and 4 only'. The View handles user interface representation and translates user interface actions into operations on the domain objects.

It takes care of presenting the model data to the user in a human-readable form. The Views are also responsible for translating between user interface actions/events and operations on the domain objects, essentially acting as a bridge that connects user inputs to actionable events that the rest of the application can respond to.

In the Model-View-Controller (MVC) architecture, the V (View) component is responsible for the user interface. It displays the information from the domain objects and receives input from the user.

On the other hand, the C (Controller) component is responsible for translating user interface actions/events into operations on the domain objects. It receives the input from the user via the View and updates the Model accordingly.

The B (Business Logic) component and domain objects are part of the Model component in MVC. They handle the business logic and define the rules and behaviors of the application.

The second option concerning the Security of the system is generally handled by other components likes Services or Middleware depending on the specific architecture and the technology stack. The third option concerning Business logic and domain objects is addressed by the Model component of MVC, which is not part of the View's responsibilities. Hence, security and business logic are not roles assumed by the View component in MVC.
