Consider the flowing reversible system  2 c A g 2B(g) AB K 1/ 2     . The above equilibrium is established in a 1L flask and at equilibrium 2 mol of each A and B are present. If 2 mol of B and 2x mol of AB2 is added further so that mol of A does not change then the value of x is (A) 6 (B) 8 (C) 3 (D) 4
