OA after discussion, good explanations will receive kudos!!
which is always used to refer to the subject before it. This is a question of parallelism. The treaty does 3 things X,Y , and Z. X,Y and Z have to have the same form. Here X=prohibits;Y=disallows. Both X and Y are action verbs. Hence Z should also be the same. Eliminate A,C and D. Between B and E, B is not a coherent thought. Treaty having been signed n 1996 by 71 states and -> This is incorrect. Now i don't know if having been is correct or not , but i will eliminate this on incorrect thought alone.
