Which set is called an empty set?
Answer and explanation
Correct answer: A set containing no element
An empty set is a set that contains no elements. Its cardinality, or number of elements, is zero. It is commonly represented by the symbols ∅ or { }. This is different from a singleton set, which contains exactly one element, and from finite or infinite non-empty sets. Therefore, option A gives the correct definition.
