The correct answer is A) the brutal conditions of slavery.
Works like that autobiography of Olaudah Equiano helped expose the brutal conditions of slavery.
Olaudah Equiano (1745-1797) was an African slave that wrote his memories as a testimony of the brutal conditions of slavery. In his autobiography, he said that he was born in Nigeria, where he and her sister were kidnapped when he was 11 years old. They were sold as slaves in Barbados, and later they were taken to the Virginia colony in NorthAmerica.
