Given that `A = {2,4,6,7,8}` and `B = {1,2,3,4}` Find `A Delta B`.
The following are the steps involved in sovling the above problem. Arrange them in sequential order.
(A) `A Delta B = (A - B) uu (B - A)`
(B) `A - B = {2,4,6.8} - {1,2,3,4}` and `B-A = {1,2,3,4} - {2,4,6,7,8}`
(C ) `A Delta B = {6,7,8} uu {1,3} = {1,3,6,7,8}`
(D) `A - B = {6,7,8}` and `B - A = {1,3}`
