Which of the following data types can NOT store the number 3?

The reason the Boolean data type cannot store the number 3 is that Boolean values are fundamentally different from numerical data types. A Boolean data type represents two states: true or false. These states are typically represented in programming languages as 1 for true and 0 for false. Since Boolean is not designed to store numerical values, it cannot hold the number 3 or any other integer or floating-point numbers.

On the other hand, Integer, Float, and Double are all numerical data types that can represent the number 3. Integer can store whole numbers, Float can store decimal numbers with floating point precision, and Double is a more precision-sensitive type than Float, capable of storing both whole and fractional numbers. Thus, these three data types can easily accommodate the value of 3, whereas Boolean is limited to only true or false values.
