Answer: (B)

The primary job of the Control Display Unit (CDU) is to allow pilots to input and manage flight management system data. The CDU serves as a user interface for pilots, enabling them to enter flight plan information, modify routes, and access various system data needed for navigation and flight management. It provides essential capabilities for pilots to interact with the aircraft's avionics, ensuring that they can effectively plan and execute flight operations. The CDU's functionality includes displaying information about the flight plan, waypoints, and performance data, while also allowing for the input of commands and modifications to the flight profile. This interaction is crucial for managing the aircraft's navigation system efficiently and effectively during different phases of flight.
