odd set is the answer

Step-by-step explanation:

=>finite set has a countable number of elements and the empty set has zero elements so, it is a definite number of elements. So, with a cardinality of zero, an empty set is a finite set.

= >The set of odd counting numbers is {1, 3, 5, 7, 9, …}. The set of even whole numbers is {0, 2, 4, 6, 8, 10, …}. The set of odd whole numbers is {1, 3, 5, 7, 9, …}. A counting number that ends in an even digit is an even number.

=> A set is infinite if and only if for every natural number, the set has a subset whose cardinality is that natural number. If the axiom of choice holds, then a set is infinite if and only if it includes a countable infinite subset. If a set of sets is infinite or contains an infinite element, then its union is infinite.

Hope this answer helps you :)

Have a great day
