Which of the following is NOT a component of a PCF?

The selection of "Bus tracker" as the correct answer highlights an understanding of the components within a PCF, or Policy Center Framework, utilized in Guidewire Insurance Suite. PCF components are fundamental elements used to design user interfaces within the Guidewire Software applications. They include various types of input fields and controls that enhance user interaction.

A contact picker, text input, and radio button are all standard components in PCF. A contact picker allows users to select contacts from a list, enhancing data entry efficiency. Text input is a straightforward field allowing users to enter text, while a radio button provides options for users to choose from a predefined set, crucial for data collection in a structured manner.

On the other hand, a bus tracker does not serve as a UI component within the PCF framework. It doesn't fit within the context of user interface elements that facilitate data input or interaction. As such, recognizing that the bus tracker is not a UI component reinforces the understanding of the primary functions of PCF elements in Guidewire applications.
