Depending on the definition, "natural numbers" can include 0 or not, but they are never negative. Since Quantity B is 0, I think it's safe to assume 0 is considered a natural number in the context of this problem. The actual GRE would never leave room for this kind of misinterpretation btw.
Solve for x and you get x >/= -26. Since x is natural, the lowest value that satisfies the inequality is 0. Thus, the correct answer is C. Alternatively, if 0 is not considered natural the lowest value of x is 1 and the answer is A. Under no circumstances will the answer be B as the original poster indicates.
