Answer:

The correct answer is option d.

Explanation:

Concentration of hydrogen ions = [H^+}=3.45\times 10^{-9} M

The pH of the solution is given by :

pH=-\log[H^+]

pH=-\log[3.45\times 10^{-19}]=8.46

The relation between the pH and pOH is given by :

pH + pOH = 14

pOH = 14 - pH

pOH=14-8.46=5.54

The pOH of the substance is 5.54.
