Selected Answer: D

The other systems listed (CAN, ASIC, and FPGA) are not directly related to the protection of electrical relays in a manufacturing facility. CAN (Controller Area Network) is a communication protocol used in automobiles and other vehicles to allow different electronic systems to communicate with each other. ASIC (Application Specific Integrated Circuit) and FPGA (Field-Programmable Gate Array) are types of computer chips that are used in a wide range of applications, including industrial control systems.
