Vedclass · Answer

(A) null set (or empty set) is a set that contains no elements.For the set of odd natural numbers divisible by $2$:An odd number is of the form $2n + 1$,where $n$ is an integer.By definition,an odd number is not divisible by $2$.Therefore,there are no odd natural numbers divisible by $2$.Thus,the set is a null set (denoted by $\emptyset$ or $\{\}$).

Which of the following is an example of the null set?
