The correct option is D. A Turing machine is a theoretical computing machine that serves as an ideal model for mathematical calculation.

Proposed by Alan Turing in 1936, the Turing machine is a mathematical model of computation. It defines an abstract machine that manipulates symbols on a strip of tape according to a set of rules. It is used to study the limits of computation and the concepts of algorithms and computability. It is not a physical machine designed for practical tasks like identifying explosives or measuring constants.

The Church-Turing thesis states that any algorithmic process can be simulated by a Turing machine. This makes the Turing machine a fundamental concept in computer science and the theory of computation. Modern computers are often described as being Turing-complete, meaning they can perform any computation that a universal Turing machine can.
