To answer this question, we need to understand the concepts of views and business components in the context of a List view with two applets displayed, a list, and a form.
A List view is a type of view in a data-driven application that displays multiple records in a tabular format. An applet is a user interface component that is used to display data and interact with users. In this case, we have two applets displayed, a list applet and a form applet.
Now let's go through each option to understand why it is correct or incorrect:
Option A) It is based on two different views - This option is incorrect because a List view can have multiple applets displayed, but it is still based on a single view. The applets within the List view can display different types of data or present different aspects of the same data, but they are all part of the same view.
Option B) It is based on two different Business Objects - This option is incorrect because a List view can display data from a single Business Object. The Business Object represents the underlying data structure and defines the operations that can be performed on the data. In this case, both the list applet and the form applet are displaying data from the same Business Object.
Option C) It can use only one business component - This option is correct because a List view can use only one business component. A business component is a logical representation of a table or view in the database and defines the data that can be displayed and manipulated in the applets. In a List view, the list applet and the form applet can both use the same business component to display different aspects of the data.
Option D) It uses two business components - This option is incorrect because a List view can use only one business component, as explained in the previous option. It cannot use two separate business components for the list applet and the form applet.
The correct answer is Option C) It can use only one business component. This option is correct because a List view can display data from a single business component, even if it has multiple applets displayed.
