You need to be able to determine just from looking at them which subnet maks you would use. The answer is most probably B, although I would like to see the exact wording of the question. The reason I say B is because the question used the temr "subnet." This tells me it is probably NOT a standard class A network using a 255.0.0.0 subnet mask. Since all of the network addresses share the 10.2.x.x patter it is safe to assume they need a /16 subnet mask.
