Because it is defined by convention at standard temperature and pressure.

Vedclass · Answer

(C) $\Rightarrow$ Water potential is denoted by the Greek symbol Psi or $\Psi$ and is expressed in pressure units such as pascals $(Pa)$.$\Rightarrow$ By convention,the water potential of pure water at standard temperatures,which is not under any pressure,is taken to be zero.$\Rightarrow$ This serves as a reference point to measure the potential of water in other systems,where the addition of solutes lowers the water potential,making it negative.
