Correct option  (a) Zero

Explanation :

The value of water potential of pure water is  highest and it is zero. water molecules possess  kinetic energy. Greater the concentration of water  in a system, greater ls its kinetic energy or its  water potential.  

If we add solute in water, the solution has fewer free water molecule and concentration of water decreases thus reducing its water potential.
