The correct answer is C. Housewives can reveal the unspoken challenges of society's expectations of women.
Housewives have been confined to their homes and chores, just like the caged bird that Mr. Wright strangled. Their responsibility was to keep the house clean, bear children and care about them, making the husband happy. Furthermore, they were supposed to stay out of the public discourse, politics, and all other serious, "manly" themes. On the top of everything, physical or emotional abuse wasn't a rare thing. All of this resulted in an ongoing frustration of American middle-class housewives, especially in the 1950's. That's one of the reasons that Trifles (1916) have been regarded as one of the first feminist dramas - and one of the reasons that housewives' lives are appropriate for writing about the oppression of women.
