C) current transformer
D) grounding electrode

The main bonding jumper is the critical link for both grounded and separately derived systems. In grounded systems, it connects the equipment grounding conductor to the grounded conductor (neutral) at the service disconnect. In separately derived systems, it connects the equipment grounding conductor to the system bonding jumper, which in turn connects the grounded conductor of the separately derived system to the grounding electrode system. The service transformer, current transformer, and grounding electrode are all important components of a grounding system, but they are not the critical link for the equipment grounding conductor.
