Final answer:
The orange cables on hybrid cars indicate high-voltage wires. They are part of the electrical system that powers the electric components of the vehicle.
Step-by-step explanation:
The orange cables on hybrid cars indicate high-voltage wires (C). High-voltage wires are used to transmit and distribute electricity at high voltages. In the context of hybrid cars, these wires are part of the electrical system that powers the electric components of the vehicle. They carry the high-voltage electricity necessary for the operation of the hybrid system.
High-voltage wires are distinguishable by their bright orange color to indicate caution and ensure proper handling due to the higher potential danger associated with high voltages. The use of such wires is prominent in transportation systems that rely on overhead or ground wires to supply electrical energy, such as trains and trolley buses.
