The correctly matched titan with his industry is:
Andrew Carnegie > Steel
- J. Pierpont Morgan was associated with banking, not oil.
- John D. Rockefeller is known for his dominance in the oil industry, not banking.
- John Sherman is known for the Sherman Antitrust Act, which was related to regulating monopolies, rather than being a titan of the oil industry.
So the correct answer is Andrew Carnegie > Steel.
