If C = {2, 4, 6, 8} and D = {8, 6, 4, 2}, which statement is correct?
Answer and explanation
Correct answer: C = D because their elements are the same
A set is determined by its elements, not by the order in which those elements are written. Both C and D contain exactly the four distinct elements 2, 4, 6, and 8. Reversing their display order does not create a new set. Therefore C and D are equal. The other options incorrectly treat order as important or misclassify a clearly finite set.
