The correct answer is B. Paine's Common Sense.
This pamphlet, written by Thomas Paine in 1776, does not fight for equal rights for races or genders - its purpose was to persuade American people to fight for their freedom from Britain - it had nothing to do with gender or race, but rather with autonomy.
On the other hand, King's I have a Dream and Washington's Atlanta Compromise Speech have to do with racial equality, whereas Stanton's Declaration of Sentiments and Resolutions has to do with gender equality.
