Which set is a singleton set and is not empty?
Answer and explanation
Correct answer: B = {0}
A singleton set is a set containing exactly one element. B = {0} contains one element, namely 0, so it is a singleton and it is not empty. The symbol ∅ in option A denotes a set with no elements. C has two elements and D has three elements, so neither is a singleton. The braces around 0 must not be confused with the empty-set symbol.
