Which statement is correct about L = {x : x ∈ N, x ≤ 3} and M = {3, 2, 1}?
Answer and explanation
Correct answer: L = M
Using N = {1, 2, 3, ...}, the condition x ≤ 3 gives L = {1, 2, 3}. M contains exactly the same three distinct elements, only written in reverse order. Set equality depends on membership, not order. Thus L = M. B is false because order is irrelevant, C is false because M contains 1, and D is false because L is non-empty.
