Final answer:
The Northern factories' demand for raw materials from the Southern states significantly impacted the Southern economy, creating a dependency on agricultural exports needed for Northern industrialization.
Step-by-step explanation:
The impact that industrialization in the Northern states had on the Southern states' economies during the 19th century is best described by the fact that Northern factories created an enormous demand for the South's raw goods. As Northern industries thrived, there was a heightened demand for cotton, tobacco, and other agricultural products which the Southern states specialized in producing. This created a strong economic interdependency, with the Southern economy heavily reliant on the agricultural exports that the Northern manufacturing sector required.
However, this interdependency also highlighted regional disparities and tensions. The industrial North favored tariffs to protect their own manufacturing, yet such tariffs were often opposed by the South, where the economy was anchored in agriculture and trade, and where such tariffs on imported goods could have adverse effects.
The correct answer to the question is B. Northern factories created an enormous demand for the South's raw goods.
