France's Saint-Domingue Was the Wealthiest Colony in the Region, in Part

France's Saint-Domingue was the wealthiest colony in the region, in part because

A) the newly independent United States could now purchase sugar from French rather than British plantations
B) French refinements in sugar production techniques made their plantations more efficient
C) the soil and climate on the island were particularly well suited to sugar cane
D) the plantation owners had enslaved the native population and thus did not have to pay to import African slaves
