The correct answer is B. They have beautiful bodies.
Explanation
The word "Although" is a contrast linking word, therefore the phrase must be completed with a sentence of opposite meaning. As a consequence, if the first sentence speaks of a negative physical attribute "Although most black women don't have a pretty face", the most appropriate for the second sentence would be a sentence in which a positive physical attribute stands out "They have beautiful bodies." So, the correct answer is B.
