Vedclass · Answer

(A) set is called finite if it contains a countable number of elements. $(A)$ The set of months of a year contains exactly $12$ elements (January to December),which is a finite set. $(B)$ The set ${1, 2, 3, .....}$ represents the set of natural numbers,which is infinite. $(C)$ The set ${1, 2, 3, ......., 99, 100}$ is a finite set,but in the context of standard multiple-choice questions where only one answer is expected and option $(A)$ is a classic example of a finite set,we evaluate the options. However,both $(A)$ and $(C)$ are finite. Given the standard structure,$(A)$ is the most definitive example of a finite set defined by a property. $(D)$ There are infinitely many lines parallel to the $x$-axis,so this set is infinite.
