The correct answer is C. Fuzzy logic.
Fuzzy logic is a form of logic that deals with approximate reasoning using degrees of truth rather than Boolean logic, which deals with only two values: true and false. Fuzzy logic is often used in artificial intelligence applications where there is a lot of uncertainty or imprecision, such as in controlling robots or diagnosing diseases.
Boolean logic is a formal system of logic based on the two values true and false. It is used in mathematics, computer science, and other fields. Boolean logic is based on the work of George Boole, who developed it in the 19th century.
Human logic is the way that humans think and reason. It is based on our experiences and our understanding of the world. Human logic is not always perfect, but it is the best way that we have to make sense of the world.
Functional logic is a type of logic that is based on functions. Functions are mathematical objects that take one or more inputs and produce an output. Functional logic is often used in computer science, where it is used to represent the behavior of programs.
None of the above is not the correct answer.
