Final answer:
Eo wants Darrow to liberate Mars from the oppressive caste system, as part of her vision for a just and free society for all Martian inhabitants.
Step-by-step explanation:
The question asks what Eo, a character in the science fiction series Red Rising, wants Darrow to do for Mars. The correct answer is b) Liberate it. Eo dreams of a free and just Mars, where the color-coded societal classes, especially the lowReds like herself and Darrow, are no longer oppressed by the Golds and other higher classes.
In Red Rising, Eo's dying wish is symbolic, inspiring Darrow to transform himself and undertake a revolutionary path. She envisions a future where all people of Mars, regardless of their class or color, can live in equality. This pushes Darrow to infiltrate the Golds and work from within to dismantle the oppressive caste system.
