(C) Given: $[H_3O^+] = 10^{-5} \; M$. First,calculate the $pH$ of the solution using the formula: $pH = -\log[H_3O^+]$. $pH = -\log(10^{-5}) = 5$. We know that at $25^{\circ}C$,the relationship between $pH$ and $pOH$ is $pH + pOH = 14$. Substituting the value of $pH$: $5 + pOH = 14$. Therefore,$pOH = 14 - 5 = 9$.
