The reform that William Lloyd Garrison is supporting in the passage above was later enacted as a result of the a. issuing of the Emancipation Proclamation (1863)
b. passage of the Reconstruction Act of 1867
c. ratification of the Fourteenth Amendment (1868)
d. passage of the Civil Rights Act of 1875

c. ratification of the Fourteenth Amendment (1868)

Explanation:

African Americans got citizenship rights in the United States through the ratification of the Fourteenth Amendment (1868). The amendment was ratified during the period of  Reconstruction and it also specified that the equal protection of the laws shall not be denied to any citizen based on race or different state's jurisdiction. This was a reminder of Garrison 's position a decade ago. "Garrisonians" may have supported changes in the other three options, but those options did not expressly grant African Americans citizenship.
