NaOH is a strong base that dissociates completely in water. Therefore, the concentration of OH- ions in the solution can be calculated as 0.235 mol/L. To find the pH, we need to use the equation: pH = 14 - pOH. 
Since pOH = -log[OH-], we can calculate pOH as -log(0.235) = 0.628. 
Therefore, pH = 14 - 0.628 = 13.37. 
Thus, the correct answer is C.
