F. None of the above

That's definitely the correct answer.

It might have been C: (C. Deal with the 120 data you have already as is) but since it has been deleted we don't know.



What's the difference between your C and the option D (use the 90 samples)

If I got 120 rows, where 30 was NULL, I'd throw those 30 away.


Those 30 are not NULL, they're "chose not to answer", usually classified as "don't know / won't answer"
