Answer: (C)

Andrew Carnegie is best known for his pivotal role in expanding the American steel industry during the late 19th century. He founded the Carnegie Steel Company, which became the largest and most profitable steel company in the world. Carnegie's innovations in steel production, including the adoption of the Bessemer process, significantly lowered the cost of steel production and improved its quality. This allowed for a surge in infrastructure development, including railroads, bridges, and buildings, thereby transforming the American economy and supporting the country's rapid industrialization.

Carnegie was also a philanthropist, donating a significant portion of his wealth to educational and cultural institutions, further underscoring his lasting impact on society beyond just business. His emphasis on efficiency, cost-cutting, and vertical integration positioned Carnegie Steel at the forefront of the American steel industry, solidifying his legacy as a key figure of the Industrial Revolution.
