Answer: A
Step-by-step explanation:
Encouraging the growth of slavery is not one of the ways that the cotton boom changed life in the South. The cotton boom caused an increase in the production of cotton, which in turn led to an increase in economic activity and a growth in population. This increased economic activity and population growth led to the development of new industries and businesses, and improved infrastructure. However, the cotton boom did not directly lead to an increase in slavery, as slavery had already been established in the South before the boom.
