That's right. Nitrite(NO2-) and hypochlorite(ClO-) and sulfate [SO4]^2- don't have 3.
B is OK. Isn't D OK too?
The following ions contain three oxygen atoms:
A) carbonate, sulfite, and nitrite
B) sulfite, nitrate, and bromate
C) sulfate, hypochlorite, and carbonate
D) chlorate, iodate, and phosphite
I know I can eliminate A and C.

I know, that is why I am confused choosing an answer.
The problem is poorly worded. If you answered correctly you would answer, carbonate, sulfite, nitrate, bromate, chlorate, iodate, and phosphite.
By merging those into answers both B and D are correct. Check to make sure there isn't a typo. That might be bromite or phosphate, chlorite, etc.
