though I can't be sure without seeing the passage first, I presume its option C) "she has a right", because it has the most assertive and passionate tone as far as I can tell.
Alliteration would be with C, the repeated letter being T at the beginning of the words
Metaphor would be A, comparing life to a walk shadow
And Onomatopoeia would be B, the sounds being clicks and clack, as well as more minor examples like pounding and leaping
