The correct answer is D.
OBJ-2.6: SCADA (supervisory control and data acquisition) networks work off an ICS (industry control system) and maintain sensors and control systems over large geographic areas. A building automation system (BAS) for offices and data centers (“smart buildings”) can include physical access control systems, but also heating, ventilation, and air conditioning (HVAC), fire control, power and lighting, and elevators and escalators. Vehicular networks are called a controller area network (CAN). A CAN uses serial communication buses to connect electronic control units and other subsystems in cars and unmanned aerial vehicles (UAV). System-on-chip (SoC) is a design where all these processors, controllers, and devices are provided on a single processor die or chip.
