Final answer:
C) Orange. Bright orange conduit or cable can indicate that high voltage power is used in the drivetrain of a vehicle.
Step-by-step explanation:
Bright orange conduit or cable can indicate that high voltage power is used in the drivetrain of a vehicle. This is because orange is a standard identifier for high voltage power systems. Manufacturers use different colors to distinguish between different voltage levels in the drivetrain. For example, green may indicate a lower voltage while orange signifies a higher voltage. These color codes help mechanics and technicians easily identify and handle the appropriate power systems in vehicles.
