What is a boolean data type and how are logical operators used?

• A. Boolean stores numeric values only; operators include ADD, SUB.
• B. Boolean stores true or false; operators include AND, OR, NOT.
• C. Boolean is used for integer arithmetic; operators include MULT, DIV.
• D. Boolean data type represents text; operators include CONCAT.

Answer: (B)

Boolean data type represents truth values used in decision making. It stores true or false, and logical operators combine or modify these values to form conditions. AND yields true only when both operands are true, OR yields true if at least one operand is true, and NOT inverts a truth value. These operators are fundamental for controlling program flow, such as in if statements and loops, where the outcome depends on these true/false conditions. The other options mix booleans with numeric or text operations, which belong to other data types: numeric arithmetic uses functions like add or multiply, and string operations use methods like concatenate. So the statement describing a boolean as storing true or false and using AND, OR, NOT is the correct one.
