The correct answer is D. They used ruthless business tactics against their competitors. John D. Rockefeller and Andrew Carnegie were able to build their massive fortunes by engaging in unfair business practices, such as price-fixing, monopolizing markets, and using their wealth to push smaller competitors out of business. These actions earned them the nickname "robber barons" because they were seen as using their wealth and power to exploit others for their own gain.
