The correct answer is B. Functionalism
Explanation:
In sociology, there are different theories and approaches that aim at explaining the relationships between women and men and in general terms the gender roles in society. In the case of the functionalist perspective this states the roles of women and men are stablishes in to help society be efficient in this way from the functionalist perspective the role of women to stay at home and grew up children while men go hunting in ancient societies support the stability and balance in society by creating an efficient labor system. Similarly, from this perspective gender roles evolve in order to preserve the stability and efficiency in society.
This perspective fits with the case presented "Women continue to assume the responsibility in the household along with a paid occupation because it keeps the household running smoothly, i.e., at a state of balance" because for this person the role of women and men is not an issue of power, domination or interaction but of function as these preserve the balance and efficiency proposed in the functionalist perspective.
