Should be B, because an alkaline solution will always be formed from a strong cation (which comes from a strong base, ex. Na+ comes from NaOH).
In option 1, Na+ is much stronger than CO3-2, so it will be alkaline.
Option 2, both ions are very strong, so they will form a neutral solution.
Option 3, Na+ and HSO4- are both very strong, but this time the solution will be acidic, because the anion has an extra H+, which can easily dissociate and form an acidic environment.
