The correct answer is C) More women started working outside the home and feminism became prevalent.
During the 1950s and 1960s, there was a significant shift in the roles of women, as more women began to enter the workforce and advocate for gender equality. This period saw the rise of the feminist movement, particularly with the publication of influential works such as Betty Friedan's "The Feminine Mystique" in the early 1960s, which challenged traditional gender roles and promoted women's rights, including equal pay and opportunities in the workplace.
