Based on the provided context, the best caption for this image would be:
"Abolitionists used the context of the Revolution to address American slavery."
The image shows an African American man holding up a paper that says "Am I Not a Man and a Brother?" This slogan was used by British abolitionists in anti-slavery efforts during the late 18th century, around the time of the American Revolution.
The other answer choices describe women's roles related to the Revolution, but do not directly connect to the content of this image portraying an abolitionist message.
Therefore, "Abolitionists used the context of the Revolution to address American slavery" is the caption that most relevantly describes how this image relates to that historical period.
