13th: abolished slavery
14th: due process and equal protection under the law.
the term "seprate but equal" came into play since racial segregation did not violate the 14th amendment.
15th: Granted african men to vote (women still couldnt vote at this time).
A new system came into play that involved people having to take literacy test or pay a tax to be able to vote which ended up still not allowing most african american men to vote.
The answer is D.
HOPES THIS HELPS!!!!!!!!!!!
