The answer would be C, Improved the conditions of the people.
Hope this helps! :)
The African-American family under slavery was generally stable and supportive (option "A" is the correct one).
Although families were stable and supportive, the slavery condition inhibited family formation. Before 1865, when slavery was prohibited, African-American slaves could not marry legally in the US, since they were not considered "people" if not "slaveholders' property". Consequently, many slaves decided to live together as husband and wife without legal union. Some enslaved people who lived in nuclear families (father, mother and children) belonged to the same owner, while others lived in near-nuclear families (the father had an owner while the mother and children had a different one). Even worse, family separation could be a possibility through the sale of one or more family members, since the slaveholders had to right to sell and purchase them.
