What type of numbers does the set of integers include?

• A. Whole positive and negative numbers only
• B. Whole positive numbers only
• C. Fractions and decimals
• D. Whole positive, negative numbers, and zero

Answer: (D)

The set of integers includes whole numbers that can be both positive and negative, as well as zero. This definition encompasses all whole positive numbers (such as 1, 2, 3, etc.), their negative counterparts (like -1, -2, -3, etc.), and the number zero itself. By including zero, the set of integers is distinct from just whole positive numbers or just negative numbers, which are improperly limited to either side of zero. Therefore, the option that states the set consists of whole positive, negative numbers, and zero correctly represents the complete definition of integers. In contrast, the other choices suggest incomplete or incorrect groupings that do not fully characterize integers or incorrectly include fractional values.
