Answer:
D) Boolean
Explanation:
Int, Float, Long and Boolean are commonly used data types in programming languages. Of these data types, the Boolean data type, named after George Boole, does not represent a numerical value. Rather it has one of two possible values, True and False. These values represent the two truth values of logic and Boolean algebra.
The Boolean data type is basically associated with conditional statements which specifies different actions to be taken depending on whether the Boolean condition evaluates to true or false. Therefore it influences the control flow of a program.
