Which statement describes entity subtypes in Guidewire?

Entity subtypes in Guidewire are designed to extend the capabilities of their supertype entities by inheriting attributes and behaviors defined in the supertype. This means that entity subtypes build upon the foundation laid by their supertype, gaining all the existing attributes and functionality while potentially adding their own unique attributes or behaviors specific to the subtype.

For example, if there is a supertype called "Vehicle," a subtype like "Car" would automatically inherit any attributes relevant to "Vehicle," such as "make," "model," and "year." The "Car" subtype could also introduce attributes unique to cars, such as "number of doors" or "trunk capacity." This inheritance system supports code reuse and simplifies the management of related data structures.

The other options do not accurately reflect how entity subtypes function in Guidewire. For instance, stating that they contain no unique attributes ignores the fact that subtypes can introduce their own specific attributes. The assertion that they cannot interact with other entities overlooks the fundamental nature of how entities relate within the Guidewire data model. Lastly, the idea that they are stored as separate files misrepresents the organizational structure of entity subtypes, as they are typically part of a hierarchical data model rather than being isolated in separate storage
