@Wilbroad256 Grammatically correct answer would be D. To simplify this the sentence says Which of the following has four COMMA meaning there is only ONE 4. With this A, and C is eliminated. Now with B if it said eight, one, and nine it would be B.
@CaribVros btw put the race area in obelisk/earth cuz it hasn't been noticed for a while. No Gen 3s are in there, and no special stuffs are in there. Would be cannon to Naruto too.
