The answer is B.
Sojourner Truth, originally known as Isabella, was born a slave in New York in about 1798. In 1826 she escaped with the aid of Quaker Abolitionists, and became a street-corner evangelist and the founder of a shelter for homeless women. When she was travelling, and someone asked her name, she said "Sojourner," meaning that she was a citizen of heaven, and a wanderer on earth. She then gave her surname as "Truth," on the grounds that God was her Father, and His name was Truth.
She spoke at numerous church gatherings, both black and white, quoting the Bible extensively from memory, and speaking against slavery and for an improved legal status for women.
