Which term is a single value of either TRUE or FALSE?

Which term is a single value of either TRUE or FALSE?

• A. Expression
• B. Conditionals
• C. Abstraction
• D. Boolean

Answer: (D)

Boolean is the data type that represents truth values—either true or false. A variable of this type holds exactly one of those two values, which is why it’s used to control decision-making in code. An expression can evaluate to a boolean, but it can also yield other types like numbers or text. Conditionals rely on a boolean result to decide which path to take, while abstraction is about simplifying details, not the actual truth value. So the term that describes a single value of either true or false is boolean.
