Even though there are 4 choices, 2 of them are the same answer, so really there are only 3 different answers to choose from.
The question has nothing to do with what the answers say other than the 2 that are the same (A & D), the numbers are there to confuse you. It has everything to do with the number of different answers you have to choose from.
There are 3 different answers ...25% 50% and 60% 100 / 3 = 33.333%

I concluded the same thing, with slightly different logic. Actually, it might be the same logic reworded.
If you assume that the answer is one of the three listed, then...
There's a 25% chance you pick Option A, which has a 33.3% chance of being right. .25*.33 = .08333 chance of being right.
There's a 25% chance you pick Option B, which has a 33.3% chance of being right. .25*.33 = .08333 chance of being right.
There's a 25% chance you pick Option C, which has a 33.3% chance of being right. .25*.33 = .08333 chance of being right.
There's a 25% chance you pick Option D, which has a 33.3% chance of being right. .25*.33 = .08333 chance of being right.
Your odds of being right = .08333+.08333+.08333+.08333 = .333333.
