The correct answer is C) Army
WAC, also known as the Women's Army Auxiliary Corps was an auxiliary unit and part of the United States Army.
It was modeled on the a similar British unit called the ATS and was seen as a good model to integrate women into the US army.
It was established in 1942 during the World War II but faced massive opposition among conservatives who believed it was immoral for women to serve in the Army alongside men.
By 1978, the WAC was completely dissolved and both male and female personnel began to work together.
