B) Off-shoring.
Off-shoring refers to the relocation of a company's business processes or manufacturing facilities from one country to another, often to take advantage of lower labor costs or other economic benefits. In this case, Domestic Industries, Inc. is relocating its manufacturing facilities from Ohio to Mexico, which would be considered an example of off-shoring.
Outsourcing, on the other hand, refers to the practice of hiring an external company to perform business functions or tasks that would traditionally be handled in-house. Domestic outsourcing refers to the hiring of a domestic company to perform outsourced tasks, while in-sourcing refers to the practice of bringing external functions back in-house.
