Final answer:
The farm plow utilized new technology for iron making, benefitting from innovations in iron production during the Industrial Revolution. Robert Fulton is known for inventing the steamship engine, which transformed transportation.
Step-by-step explanation:
The invention that utilized new technology for iron making was the B. farm plow. Innovations in iron production during the Industrial Revolution, such as using coke from coal in smelting processes, dramatically lowered the cost of iron and increased its availability. This led to the development of stronger and more efficient tools, including farming implements like the plow. This greatly enhanced agricultural productivity by allowing heavier soils to be farmed more efficiently. The availability of new building materials such as iron and steel was crucial in the development of new construction techniques and the emergence of new workplaces like the mechanized factories.
Regarding the multiple-choice question about Robert Fulton, the correct answer is C. the steamship engine. Robert Fulton is best known for his work on steamship technology, which revolutionized transportation and played a significant role in the Industrial Revolution.
