The constitutional amendment directly led to the first african american elected to the u. s senate a. 13th amendment b. 14th amendment c. 15 amendment d. 16th amendment

Hello,

The answer is option C "15th amendment".

Reason:

The 15th amendment allow the first African American to be elected the U.S senate. The answer is not option A because the 13th amendment covers a much broader array of labor arrangements and social deprivations. Its not option B because the 14th amendment is addresses the equal protection and rights of former slaves. Its also not option D because the 16th amendment tax is money that is paid to the government and will be added when buying or owning something valuable. Therefore the answer should be option C! 

If you need anymore help feel free to ask me!

Hope this helps!
