OK. If you know (i) is true (you're right), then you KNOW (III) can't possibly be right. Right? Because if CH3NH2 is a stronger base than NH3, then CH3NH2 must give a higher concn of OH^- than NH3. Now what about (ii)?
If CH3NH2 is a stronger base than NH3, then the conjugate acid of CH3NH2 must be weaker than the conjugate acid of NH3. By knowing (i) is right, you should be able to reason about the other two.
