Final answer:
The time period described saw widespread segregation and limited civil rights for African Americans, despite the abolition of slavery and voting rights granted to black men through constitutional amendments. Women's suffrage was not achieved until 1920.
Step-by-step explanation:
The social practices of the time period described seemingly revolve around the issue of segregation and limited civil rights, especially for African Americans. While the Thirteenth Amendment abolished slavery and the Fifteenth Amendment granted black men the right to vote, these changes did not immediately eliminate discriminatory practices such as segregation and disenfranchisement, particularly in the South.
Segregation was legally enforced in many states, leading to unequal opportunities and treatment in public facilities and education. African Americans faced voting restrictions and other forms of discrimination, even a century after the 15th Amendment was passed. Women's suffrage was also an ongoing battle, with the Nineteenth Amendment in 1920 eventually granting women the right to vote.
Given these considerations, the statement that most accurately reflects the social practices of the time period is:
d) Segregation was widespread.
