Which of the following is a real number?

0
Imaginary
1
Square root of -1

The correct answer is: 1

Real numbers are defined as numbers that can be expressed as infinite decimal representation. This includes numbers such as whole numbers, natural numbers, integers, fractions, and decimal numbers. Option A is the only real number listed as it is a whole number, and whole numbers are a subset of real numbers. Option B, Imaginary, is not a real number as it cannot be represented on the number line and does not follow the rules of real numbers. Option D, square root of -1, is known as an imaginary number, and as mentioned before, is not a real number since it cannot be represented on the number line.
