Final answer:
The 260,000 free blacks in the South by 1860 were barred from voting or holding public office.
correct answer is C
Step-by-step explanation:
The restriction that was placed on the 260,000 free blacks in the South by 1860 was that they were barred from voting or holding public office.
After the end of Reconstruction, African Americans began to see many of their new freedoms disappear, and Southern states used various tactics to deny them the vote.
These tactics included requiring voters to own property, pay a poll tax, and pass literacy tests, all of which effectively prevented many African Americans from voting.
correct answer is C
