• A. didn't they?
• B. did they?
• C. didn't he?
• D. did he?

Answer 1

Answer:

B. did they?

No one helped me, did they?

This is a tag question. The main sentence is negative ("No one helped me"), so the tag question is positive ("did they"). The auxiliary verb "did" is used because the main sentence is in the past tense.
