Best answer
Right answer is (c) Flow visualization

The best explanation: A flow can be categorized into laminar or turbulent by seeing it. So, the flow of air should be made visible by some flow visualization techniques. In the case of CFD, it can be easily seen from the resulting plot of flow properties.
