Which of these is a whole number?

• A. -3
• B. 4
• C. 3.5
• D. 0.9

Answer: (B)

A whole number is defined as a non-negative integer, which includes zero and all positive integers. Whole numbers do not include negative numbers or fractions. In this case, the only number listed that meets the criteria for being a whole number is 4. It is a positive integer and does not contain any decimal or fractional component. Negative numbers, like -3, are not considered whole numbers, nor are decimal values such as 3.5 and 0.9, which also fall outside the definition of whole numbers due to their fractional parts.
