The correct answer is:
4. Anthony argues that without the fundamental right to vote, women lose all other rights of citizenship.
In "The Trial of Susan B. Anthony," her emphasis is on how the denial of the right to vote undermines her status as a citizen and strips away her other rights. She highlights the fundamental nature of voting as a cornerstone of citizenship and implies that its absence leads to broader implications for women's rights and status in society. This focus on the interconnectedness of voting rights and citizenship rights sets her argument apart from the other options.
