Show answer & explanation
Correct answer: B
The symmetric difference of two sets includes elements present in either set A or B, but not in both simultaneously.
Set A = {1, 2, 3, 4, 5, 6, 7, 8} and Set B = {1, 3, 5, 6, 7, 8, 9}.
The intersection (common elements) is {1, 3, 5, 6, 7, 8}. Subtracting these from the union leaves {2, 4, 9}.
