Answer:
Step-by-step explanation:
B) Variable.
A variable is a named memory location in a computer program that stores a value that can vary. The value of a variable can be assigned, updated, and accessed throughout the program. Variables are used in programming to store data that can be used in calculations, comparisons, and other operations.
Input and output are terms used to describe the flow of data into and out of a computer system, respectively. Logic refers to the reasoning or decision-making processes used in computer programming. While variables may be used in both input and output operations and in logic, they specifically refer to named memory locations that store values that can vary.
