Which of the following is an integer?

Explanation:
An integer is any whole number, including zero, that has no fractional part. Among these options, zero fits that definition exactly. It is a whole number and belongs to the integers. The first option, 1/2, is a fraction equal to 0.5, not a whole number. The third option, the square root of 2, is irrational (about 1.4142...), not a whole number. The fourth option, pi, is also irrational (about 3.14159...), not an integer. Therefore, zero is the integer.
