1. Why did you learn English to attend this school?
2. How long has Eve lived in her flat?
3. Last night, did you get the news about what will happen when you get home from the army?
I believe it is C, an in-text citation because it isn't A since you've cited the source, it's not a full works cited like D, and it's not in quotes so it's not a direct quotation like B. Hopefully that helps you out!
