B
Explanation:
If you add solvent to the solution, the volume (of solution) increases, and the number of moles of solute stays unchanged.
Therefore concentration (in moles per litre) will reduce. So the answer is B.
The question is badly written though - A and D are the same (they should be different, surely?).
Also, "amount of moles" - should really be "number of moles" (or "amount of substance") - but....moles of what? Solvent? Solute?
