If G={5}, what type of set is G?
Answer and explanation
Correct answer: Singleton set
A singleton set is a set containing exactly one distinct element. In G={5}, the only element listed is 5, so the cardinality of G is 1 and G is a singleton set. It is not empty because it contains 5, and it is not infinite because it has only one element. The label universal set cannot be decided without a stated universal context. Therefore option A is correct.
