B)1850.
C)1900.

Accepted Answer

The pasteurization of milk and milk products became a widespread requirement in the United States in the early 1900s, as a response to the high incidence of tuberculosis and other diseases that were transmitted through raw milk consumption. While there were some earlier efforts to promote pasteurization, it was not until the 20th century that it became a mandatory practice in many cities and states.
