what do the 15th, 19th, and 26th amendments have in common?

a voting rights
b religious rights
c african american rights
d womens rights

The correct answer is "a voting rights."

All three amendments specifically address voting rights and expand the franchise to certain groups of individuals:

- The 15th Amendment (ratified in 1870) prohibits the denial of the right to vote on the basis of race, color, or previous condition of servitude.
- The 19th Amendment (ratified in 1920) grants women the right to vote, thereby providing gender equality in voting.
- The 26th Amendment (ratified in 1971) lowers the voting age from 21 to 18, ensuring that individuals 18 years and older have the right to vote.
