Final answer:
The correct ranking of the complexity of the communication models is Model 2, Model 1, and Model 3.
Step-by-step explanation:
The correct ranking of the complexity of the three communication models is option 3) Model 2 is the simplest, Model 1 is intermediate, and Model 3 is the most complex.
In this ranking, Model 2 represents a relatively simple communication model, with a straightforward flow of information.
Model 1 is considered intermediate in terms of complexity, indicating a slightly more intricate communication process.
Model 3 is ranked as the most complex, suggesting that it involves advanced elements and a higher degree of intricacy compared to the other models.
