Step 1: Understanding the question.
The question is asking about the data type used to represent truth values. In programming, especially in Python, the Boolean data type is used to represent truth values, typically either True or False.
Step 2: Analyzing the options.
(A) Boolean: Correct — Boolean is used to represent truth values like True and False.
(B) float: This is incorrect. A float is used for representing decimal numbers.
(C) integer: This is incorrect. Integers represent whole numbers, not truth values.
(D) complex: This is incorrect. Complex data types are used to represent numbers with both real and imaginary parts.
Step 3: Conclusion.
The correct answer is (A) Boolean, as it is the data type used to represent the truth value of an expression.
