Correct Answer: A
Solution :
On the basis of the information given in the questions, we find that C and D can take three positions as shown in the diagram following the restriction that C and D cannot be together. If P is true, then both Q and R have to be true. For S to be true, either Q or R must be false. Hence, if P is true, S cannot be true.You need to login to perform this action.
