Which option correctly identifies equal sets?
Answer and explanation
Correct answer: Equal sets must contain exactly the same elements; their order does not matter.
Two sets are equal precisely when they have the same elements, meaning every element of the first set belongs to the second and every element of the second belongs to the first. The order of listing is irrelevant because sets are unordered collections. For example, {1, 2, 3} and {3, 1, 2} are equal, whereas {1, 2} and {1, 3} are not equal even though both have two elements.
