Both options A and B are present in the idea exposed in The Anti-Suffragist by William Lloyd. But, when it comes to this specific passage, the answer that seems to be correct is B. show that objections to suffrage are based upon stereotypical assumptions about women.
This passage is about the misconception that women would rather worry - only - about domestic affairs and leave the thinking to men, since it is a hard task.
The woman characterized in this poem, Remonstra, ends up proving the exact opposite, however. She works so hard fighting against the suffrage, organizing speeches and committees, that everyone else admires her intelligence and abilities. People even say she would be better at running a city than half the men in office. The stereotype she is fighting so diligently to maintain is, thus, destroyed.
