  • BEvery integer is a whole number.
  • CNegative numbers are whole numbers.
  • DZero is a negative integer.

Step-by-Step Solution

Answer: A) Every whole number is an integer.

Key idea: Integers on the number line

Draw a line, mark zero in the middle, and step off equal distances. To the right: 1, 2, 3, …. To the left: −1, −2, −3, …. Every integer has its own spot. The further left, the smaller the integer. The further right, the larger. This single picture is the foundation for everything else in this topic — when in doubt, draw the line.
