Which of the following is a whole number? Choices: (A)0 (B)sqrt 5 (C)𝜋 (D)–9

Identify Whole Number: We need to identify which of the given choices is a whole number. A whole number is a non-negative integer, which includes 0, 1, 2, 3, and so on.Evaluate Choices: Let's evaluate each choice: (A) 0 is a whole number because it is the smallest non-negative integer.Choice (A): (B) The square root of 5 (sqrt 5) is not a whole number. It is an irrational number because it cannot be expressed as a fraction of two integers and its decimal representation is non-terminating and non-repeating.Choice (B): (C) Pi (π) is not a whole number. It is an irrational number known for being the ratio of the circumference of a circle to its diameter, and it also has a non-terminating and non-repeating decimal representation.Choice (C): (D) –9 is not a whole number. Although it is an integer, whole numbers are defined as non-negative, and –9 is negative.Choice (D): Based on the evaluations, the only whole number from the choices is (A) 0.

Identify Whole Number: We need to identify which of the given choices is a whole number. A whole number is a non-negative integer, which includes $0, 1, 2, 3,$ and so on.
Evaluate Choices: Let's evaluate each choice: $\newline$ (A) $0$ is a whole number because it is the smallest non-negative integer.
Choice (A): (B) The square root of $5$ ( $\sqrt{5}$ ) is not a whole number. It is an irrational number because it cannot be expressed as a fraction of two integers and its decimal representation is non-terminating and non-repeating.
Choice (B): (C) Pi ( $\pi$ ) is not a whole number. It is an irrational number known for being the ratio of the circumference of a circle to its diameter, and it also has a non-terminating and non-repeating decimal representation.
Choice (C): (D) $–9$ is not a whole number. Although it is an integer, whole numbers are defined as non-negative, and $–9$ is negative.
Choice (D): Based on the evaluations, the only whole number from the choices is $(A) 0$ .
