The correct answer is C. and D. Conflict theory is descended from Marxism; it has a materialistic and dialectic view of society, which it views critically. The male/female division of labor presents an opportunity to denounce an ongoing injustice. Stuctural functionalism, on the other hand, is a theoretical perspective that view society as a complex system of interrelated subsystems. It would be interested in how the division of labor in domestic economies affects society as a whole.
A. and B. are not correct. Queer theory would be interested in deviations from the traditional male/female dualism, while symbolic interactionism is more focused on small-scale interactions between individuals.
