You create Microsoft Windows-based applications. You are designing an application that permits insurance agents to provide insurance quotes to prospective customers. The application permits insurance agents to survey the customer and enter the customers responses into the application. Each customer response adjusts the computed level of risk for the customer depending on how the customer answers the question.

The application must meet the following requirements:

The application must continuously display a thermometer indicating the level of risk. The prospective customers risk must be updated after each question. The application must ensure that the user interacts with the thermometer component as little as possible.

You need to evaluate a user interface design for the thermometer component of the application. What should you do?

A.
Design the thermometer component as a movable tool Window that is always displayed as the top most Window.

B.
Design the thermometer component as a part of the main questionnaire form that is always visible.

C.
Design the thermometer component to be displayed as a modal Window when the insurance agent clicks a button.

D.
Design the thermometer component to display a non-modal Window that can be dismissed by the insurance agents when they are ready to ask the next question.
