Which option is not an empty set?
Answer and explanation
Correct answer: {0}
The notation {0} means a set containing the single element 0, so it is not empty. By contrast, ∅ has no elements. Under the usual convention that natural numbers begin at 1, no natural number is less than 1, and a square cannot have three sides. Therefore option A is the only non-empty set.
