In that case yes. But in the question posed, only one answer is 50%. That means you only have a 1/4 chance of randomly (assuming random means answers A,B,C and D are equally likely to get picked) picking answer B. Since you only have a 25% chance of picking B, B cannot be correct.
It's a paradox, which means it has no solution.
The only way you can make this question solvable is to say that random means something else, for instance a random distribution where you have a 10% chance of picking A, a 20% chance of B, a 60% chance of picking C and a 15% chance of picking D. In that scenario, C would be the correct answer. But a situation like that is the only way this question is solvable.
