Answer:
B.
Step-by-step explanation:
It sounds better for me, and judging by the ratings on the guy who answered this question above, I assume he's incorrect. So, I guess it's a. Let me know if this is wrong, since I'm doing the assignment right now. But it doesn't matter anyway, once I finish it, I will come back to this question and let you know if it was either a or b.
Edit: nevermind, it was letter b. I put A and I got it wrong.
