The correct answer is A. A system that has no energy exchange nor matter exchange with the outside world is an isolated system ； A thermodynamic system that has no heat transfer with the outside world is called an adiabatic system ； A thermodynamic system that has material exchange with the outside world is an open system ； A thermodynamic system that has no mass exchange with the outside world is a closed system; rigid-body systems are irrelevant to this problem.
Answer: A. Isolated system. Option A refers to a system that has no energy or mass exchange with the outside world; Option B refers to a system that does have mass exchange with the outside world; Option C is unrelated to this question and falls under the category of mechanics; Option D refers to a system that has no mass exchange with the outside world.
