Final answer:
The standard that demands maximum efficiency and can only be achieved if everything operates perfectly is the Ideal standards.
Step-by-step explanation:
The standard that demands maximum efficiency and can only be achieved if everything operates perfectly is the Ideal standards. Ideal standards are theoretical standards that assume no inefficiencies or faults in the system. They represent the highest level of efficiency and are used as benchmarks for comparison. To illustrate, let's consider an example: if a manufacturing company sets an ideal standard for production, it would mean that every process is running flawlessly and no time or resources are wasted.
