The correct answer is d. Civil Rights Act of 1875.
The Civil Rights Act of 1875 was an act signed on March 1st of 1874 in the U.S. this act was especially relevant because it was the first act that guaranteed African Americans had equal treatment in transportation and in general public places, this included African Americans right to receive accommodations and services in buses, trains, among others and enjoy public places such as restaurants in the same way white population did, which implies the law began protecting African American basic rights of citizenship. Therefore, it was the Civil Rights Act of 1875 the one that gave black citizens the right to ride trains and use other public facilities.
The Civil Rights Act of 1875 granted African Americans the right to access public accommodations, including transportation, and aimed to ensure equal treatment. However, the Act was later ruled unconstitutional by the Supreme Court in 1883. This legislation was a major step towards civil rights, though its enforcement faced significant challenges.
