The correct match is:
- Andrew Carnegie > Steel
Andrew Carnegie was a key figure in the steel industry during the late 19th and early 20th centuries. The other options are incorrect:
- J. Pierpont Morgan was primarily involved in banking and finance.
- John D. Rockefeller is associated with the oil industry, not banking.
- John Sherman is known for the Sherman Antitrust Act, which aimed to combat monopolies, but he is not correctly associated with the oil industry.
So, the only correct pairing is Andrew Carnegie with steel.
