Final answer:
Mary Wollstonecraft (option A) articulated her belief in the equality of the sexes and the need for women's education in her support for the women's suffrage movement, marking her as a foundational figure in feminist thought.
Step-by-step explanation:
In her books and essays in support of the women's suffrage movement, Mary Wollstonecraft articulated her belief that a society dominated by males will always lead to the oppression of women. Mary Wollstonecraft, an English writer, philosopher, and advocate of women's rights, challenged the perception that women were naturally inferior to men largely due to the lack of education provided to them.
In her seminal work, A Vindication of the Rights of Woman (1792), she presented the idea that men and women should be seen as rational beings deserving of equal opportunities, particularly in education. Wollstonecraft's thoughts laid the groundwork for future feminist movements and made her one of the earliest and most significant figures in feminist thought.
