Correct Answer
A. \([1,3]\cup[7,9]\)
Concept
(B) does not include (3) and (7), so they remain in (A-B). The result is \([1,3]\cup[7,9]\).
Why this answer is correct
The correct answer is A. \([1,3]\cup[7,9]\). (B) does not include (3) and (7), so they remain in (A-B). The result is \([1,3]\cup[7,9]\).
