Answer:
E. Slaves were required to grow crops on plantations.
Explanation:
Pro-slavery Americans claimed that slaves were essential to the supply of agricultural products in the country. This is because it was the slaves who did the whole process of sowing, maintaining, harvesting, processing and distributing agricultural products from southern crops. These people who defended slavery, claimed that freeing the slaves would dissolve all this labor and block the productivity of the national agricultural sector.
