The correct response is:

It is an integer but not a whole number.

In detail:

  • -9 is an integer because integers include all whole numbers and their negative counterparts.
  • Whole numbers are defined as non-negative integers, which means they include 0 and positive numbers only. Since -9 is negative, it is not considered a whole number.
