Which action should you take?

Choose only one option

Simulated environment testing is only useful for non-aerospace applications

Simulated environment testing can replace physical testing entirely

Simulated environment testing replicates real-world scenarios to assess system behavior, but ensuring accuracy requires high-fidelity models and appropriate calibration

Simulated environment testing is irrelevant for space applications
