First, we need to find the concentration of hydroxide ions in the solution.

One mole of KOH dissociates into one mole of K+ ions and one mole of OH- ions.

0.0010 mole of KOH yields 0.0010 mole of OH- ions.

The volume of the solution is 1.00 liter, so the concentration of hydroxide ions is:

[OH-] = 0.0010 mole / 1.00 liter = 0.0010 M

Using the equation for calculating pOH:

pOH = -log[OH-] = -log(0.0010) = 3

Since pH + pOH = 14, we can calculate pH as:

pH = 14 - pOH = 14 - 3 = 11

Therefore, the pH of the solution is 11 and the pOH of the solution is 3.

The correct answer is D.
