Which of the following best defines an integer?

Explanation:
Integers are whole numbers that include zero and all of their negative and positive counterparts. That means numbers like -3, 0, and 7 are all integers. This is why the description that includes a positive or negative number and 0 fits best. Fractions and decimals have parts beyond a whole number (like 1/2 or 3.14), so they aren’t integers. Natural numbers are the counting numbers, usually starting at 1 (and sometimes including 0), so they don’t cover negative values and aren’t the full set of integers.
