Which of the following statements is true about the container widget hierarchy?

The statement that Detail View and List View can be directly contained by screen and secondary containers is accurate because of the structure and purpose of these container types in the Guidewire user interface framework. In this hierarchy, the screen acts as a primary container that organizes the overall presentation of data and UI components, while secondary containers are intended to facilitate the grouping and management of related UI elements, such as Detail Views and List Views. By allowing these views to be placed within either of these containers, Guidewire promotes a flexible and modular design that can enhance user experience and the overall layout of the application.

When considering the other options, it’s clear that the container hierarchy has specific rules defining how various widgets are related. Input sets, for example, can be utilized in multiple widget types beyond just Card views. Atomic widgets are designed to be flexible and can be included in various container types rather than being limited to secondary containers. Lastly, while Detail Views can certainly incorporate primary containers, they are not restricted exclusively to these; they can also accommodate other structures within the layout. Thus, the selected answer regarding the container widget hierarchy aligns accurately with the designed architecture and functionality within Guidewire's framework.
