You work as the Enterprise application developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. Your responsibilities at Domain.com include the testing and stabilization of applications. Domain.com operates as a medical technological company that manufactures electronic scanning equipment for medical use.
You are currently planning the performance of integration testing on a Microsoft Windows Forms application. This application is designed to allow doctors to perform internal gastro scopes. This application makes use of a controller to operate the scanning device that is inserted into the patient via the oral cavity. The exhibit below illustrates a component diagram of the application.

You now need to determine the component dependencies based on this design.

What should you conclude?

A.
The application depends on the controller and the gastro scope.

B.
The application depends on the controller, and the controller depends on the gastro scope.

C.
The gastro scope depends on the controller, and the controller depends on the application.

D.
The gastro scope depends on the controller and the application.

Explanation:
According to the diagram the direction of the arrow shows the dependency relationship. In this case the arrow is drawn from the Application component to the Controller component. This means that the application depends on the controller. And the other arrow is drawn from the Controller component to the Gastro Scope component which in turn means that the controller is dependent on the gastro scope.
Incorrect answers:
A: This option would see the arrow drawn from the Application component to the Controller and Gastro Scope components.
C: This option would see the one arrow drawn from the Gastro Scope component to the Controller component and another arrow from the Controller component to the Application component.
D: This option would see the arrow drawn from the Gastro Scope component to the Controller and Application components.
