There has to be a correct answer, therefore the chance of answering correctly will never be 0%, thus we remove B out of the equation;
There are two equal answers, so that actually merges them into one: 2/4 answers account for 50% of the whole thing, but seeing as option B has been neglected by us, and A and D are only one answer now, that leaves us with a chance of 1/2 (=50%), either you get (A+D) right or C right.
Final answer is C, I'll take that money now Regis, thanks
