The correct answer is D.
Muller v. Oregon was a judicial case that led to the enactment of a landmark decision by the US Supreme Court in 1903. It reaffirmed the allotment of less working hours to women than to men, and refused to allow women to freely negotiate their working contracts as men did. The jury understood that the abilities and functions of women in society were different than those of men, and therefore women should 'be protected' by working less.
