Answer:
I believe the answer is D.
Explanation:
I think this because when you're applying to college, you need to know who you are and what goals you want to accomplish. It wouldn't be A because who cares who's reading it? It wouldn't be B because you aren't writing for entertainment. It wouldn't be C because they don't really need to know about what you've already done. More so, they need to know why they need you. So, the answer is D. Prove to them that you want to do this.
