Which statement is true about inline input set widgets?

Inline input set widgets indeed inherit the parent root object in Guidewire. This characteristic allows them to access and manipulate data within the context of their parent, which is essential for maintaining data consistency and ensuring that the widgets function correctly within the interface. By inheriting properties from the parent root object, these widgets are able to reflect the current state and can interact with the underlying data model effectively. This inheritance is key to how the widgets are designed to work within the Guidewire ecosystem, supporting a fluid and dynamic user experience.

The other options do not accurately describe the nature of inline input sets. While they can be reused and may often be used in isolation, these traits are not defining characteristics of inline input sets, and the ability to inherit properties is a fundamental aspect that sets them apart.
