50% chance of being correct because 2 of the 4 options are the same value.

mcordeiro0's answer doesn't work. You can't just ignore answers A and D, so there's still only a 1 in 4 chance of picking B at random. The only way this works out is if A and D are treated as unique answers. In that case, the key determines whether or not you're wrong, and the chance of a random answer being correct is 25%.

B. Since a and d are the same, it can't be either of those. Then you have either b or c, it's 50 50.

But Ray, there's only one "50%", therefore you would have a 25% chance again. And just because 2 answer are the same doesn't mean they have to be eliminated.
