i believe it is a sentence fragment and subject verb disagreement
Explanation:
it seems to be asking for you to explain an issue that you disagree with and want to be fixed, like racism or homophobia. The second part is sayibg would you devote yourself to a cause like joining a anti-racist group and protesting or raising awarness for example- just pick a topic you disagree with and why
id say C. stands both for itself and for something else
