Please drag and drop the selected option in the right place or type it instead
null set
singleton with null set

Correct Answer

(1) null set
(2) singleton with null set

Explanation

We must distinguish between ∅ and {∅}. Although set ∅ is a null set (i.e., it contains no element), the set {∅} is a singleton whose one element is the empty set ∅. Similarly, {0} is a singleton.
