Integers are defined as the set of whole numbers that include both positive and negative numbers, as well as zero. This means that integers comprise the entire spectrum of whole numbers in both directions from zero: the positive whole numbers (1, 2, 3, ...), the negative whole numbers (-1, -2, -3, ...), and zero itself. This comprehensive classification distinguishes integers from other types of numbers.

Other options do not accurately encompass the definition of integers. Whole numbers only refer to non-negative integers, omitting negative numbers and zero. Only negative numbers contradict the definition by excluding positive numbers and zero entirely. Prime and composite numbers specifically refer to categories of whole numbers that are greater than one and do not encompass negative integers or zero. Therefore, defining integers as whole numbers and their opposites captures the full range of what integers represent.
