Answer:
The correct option is D) Models are not the "real thing" so it will never correctly represent the system in all respects.
Explanation:
A scientific model might be a physical or a mathematical representation of any complex scientific theory or explanation. A model is generated so that we can understand a scientific phenomenon easily and in a better way. A model can be used to understand about any scientific topic.
However, no matter how excellent a scientific model be, but it cannot fully understand the complex interactions that might occur in systems. For example, a model of a human organ cannot fully illustrate the different interactions that the organ might be undergoing with different molecules.
