Which set is finite?
Answer and explanation
Correct answer: Set of months of a year
The governing concept is finiteness: a finite set has a fixed and limited number of elements. A year has exactly twelve months, so its set of month names can be completely counted and has 12 elements. The integers and natural numbers continue indefinitely, and the real numbers are also infinite. Therefore only the set of months of a year is finite, making option C correct.
