The set of all rational and irrational numbers.

Explanation:
Real numbers are all the numbers that can be placed on the number line. They include both rational numbers (like 2/3, -5, or 0) and irrational numbers (like sqrt(2) or pi). The union of these two types covers every point on the number line, which is exactly what real numbers are. Imaginary numbers are multiples of i, and complex numbers with a nonzero imaginary part aren’t on that line. So the set that contains all rational and irrational numbers is the real numbers.
