Choice C is the best answer. Woolf uses the word "we" to refer to herself and educated women in English society, the "daughters of educated men"(line 64,"the daughters of"). Woolf wants these women to consider participating in a changing workforce: "For there, trapesing along at the tail end of the procession [to and from work], we go ourselves" (lines 23-24,"appreciation...And that"). In using the word "we" throughout the passage, Woolf establishes a sense of solidarity among educated women.
Choice A is incorrect because Woolf does not use "we" to reflect on whether people in a group are friendly to one another; she is concerned with generating solidarity among women. Choice B is incorrect because though Woolf admits women have predominantly "done their thinking" within traditional female roles (lines 64-69, "are facts... to our"), she does not use "we" to advocate for more can-dor among women. Choice D is incorrect because Woolf does not use "we" to emphasize a need for people in a group to respect one other; rather, she wants to establish a sense of solidarity among women.
