The Web-based client application is used for end-user interaction. The Web-based client application uses two business logic components named Order and Customer.
Each customer can have multiple orders.
Each order belongs to a single customer.
The business logic components use a DAC Web service.
The business logic components make data available to the Web-based client application.

You receive a deployment diagram as shown in the following exhibit. (Refer to the Exhibit.) You need to evaluate the diagram to ensure that it complies with the specifications. What should you conclude?

A.
The diagram complies with the specifications.

B.
The diagram is incomplete. It needs a dependency from the Web client component to the Microsoft Data Access component.

C.
The diagram is incomplete. It needs a dependency from the Data Access component to the Order component.

D.
The diagram is incomplete. It needs a dependency from the Order component to the Web-based client application.
