>>12730879B is wrong, because if there's 4 options but only 1 is correct there should be, at the very least, 25% chances.
A and D isn't the right answer either, because having two options that are the same means that it doesnt matter which you pick, both are wrong or right, something that shouldn't be possible in a multiple answer question.
however, since the key of the question is that you must pick at random, which brings us back again at 1/4 chances, so 25% chances.
