Answer:
The correct answer is B. When the Civil War broke out, the South relied heavily on agricultural exports to Europe.
Step-by-step explanation:
The South had an agrarian economy that exported to the international market, it was a large producer of cotton and, to a lesser extent, tobacco and sugarcane. The food production was mostly of grain, pigs, livestock and vegetables. The southern states produced 155 million dollars in manufactured goods in 1860, mainly derived from the grinding of grain in local mills, wood, processed tobacco, goods made with cotton and products destined for the naval sector such as turpentine.
Due to this situation, the South fundamentally sought the extension of the slave system and free trade for the export of raw materials and the importation of manufactured goods without barriers to and from Europe, especially France and Great Britain.
