The correct response is:
The Fourteenth and Fifteenth amendments granted citizenship to all and voting rights to African American males.
The Fourteenth Amendment, ratified in 1868, granted citizenship to all persons born or naturalized in the United States, including formerly enslaved people, and provided equal protection under the law. The Fifteenth Amendment, ratified in 1870, prohibited the federal and state governments from denying a citizen the right to vote based on "race, color, or previous condition of servitude."
