1.	`A = {x : 2 lt x lt 8 " and " x in N}` and `B = {x:3 lt x lt 9 " and " x in W}`. Find `(A - B) nn (B - A)`. the following are the steps involved n solving the above problem. Arrange them in sequential order. (A) `A = {3,4,5,6,7}` and `B = {4,5,6,7,8}` (B) `A - B = {3}, B - A = {8}` (C) `A - B = {3,4,5,6,7}-{4,5,6,7,8}, B-A ={4,5,6,7,8} - {3,4,5,6,7}` (D) `(A - B) nn (B - A) = phi`A. ABCDB. ACBDC. ABDCD.
