Answer:
B) Jim Crow laws
Step-by-step explanation:
The first steps toward official segregation came in the form of “Black Codes.” These were laws passed throughout the South starting around 1865, that dictated most aspects of Black peoples’ lives, including where they could work and live. The codes also ensured Black people’s availability for cheap labor after slavery was abolished. Segregation soon became an official policy enforced by a series of Southern laws. Through so-called Jim Crow laws (named after a derogatory term for Black people), legislators segregated everything from schools to residential areas to public parks to theaters to pools to cemeteries, asylums, jails, and residential homes. There were separate waiting rooms for white people and Black people in professional offices and, in 1915, Oklahoma became the first state to even segregate public phone booths.
