Which option correctly shows the empty set?
Answer and explanation
Correct answer: ∅
The governing concept is the empty set, which contains no elements and is written as ∅. The symbol 0 is a number, not a set. The notation {0} represents a singleton set containing the element zero, so it has one element. Likewise, {∅} contains the empty set as one element and is also not empty. Hence option C alone denotes a set with no members.
