The correct answer is C. Technology
Step-by-step explanation:
In the economy, technology includes machines, infrastructure or similar that improve production rates which means more units are manufactured in a shorter time or makes production cheaper by replacing high-cost technology or workers. This is the opposite of labor because technology only involves objects or machines rather than workers. This implies the case presented is an example of growth caused by technology because in this case, it is the robotic machinery the one that increases the production of cars.
