Which statement about equal sets is correct?
Answer and explanation
Correct answer: They contain exactly the same elements
Two sets are equal precisely when they contain the same elements. The order in which elements are written does not matter, and repeated listing of an element does not create a new element. Equal sets need not be empty; for example, {1, 2} and {2, 1} are equal. Hence, option B is correct.
