Which term denotes true or false, named after George Boole?

• A. Binary
• B. Logic
• C. Boolean
• D. Truth

Answer: (C)

Boolean values are the true/false building blocks used in logic and programming, and the term comes from George Boole, who introduced Boolean algebra to formalize how these truth values combine with logical operators. In practice, a boolean represents a variable that can be either true or false, and it’s the foundation for conditions, control flow, and truth tables. Binary, in contrast, refers to base-2 numeric representation and isn’t specific to truth values. Logic is the broader field of reasoning, not the label for this particular data type. Truth describes the quality of being correct or veracious, not the data type name.
