What was a result of the invention of the cotton gin?

A decrease in the use of slaves in the South

B. An increase in the price of cotton

C. A decrease in cotton production

D. An increase in the use of slaves in the South

D. An increase in the use of slaves in the South

The correct answer should be either a or b.

A - The amount of slaves went down because the cotton gin replaced many people.

B - When something is mass-produced, you can make it for less and earn more money

C - This option just doesn't make sense considering the fact that cotton gins were a positive invention. If they weren't positive they wouldn't have kept them.

D - This could be true but it is very unlikely considering the context of the question. As I stated above, the cotton gin replaced many slaves (everywhere, not just in the South).

I am more leaning toward A because that's what I learned; but, B could also work.
