To start you must know that KOH is a base not an acid, so the solution is basic.

Now you can calculate the pH from these two equations:

1) pOH = - log [OH-]

2) pH + pOH = 14 => pH = 14 - pOH

1) pOH = - log (0.01) = 2

2) pOH = 14 - 2 = 12

Then, the answer is the option 4, the solution is basic with a pH greater than 7 (in fact, by definition a basic solution has pH greater than 7).
