Answer

Explanation:

Step1: Identify highest relative frequency

The relative frequencies are: Pilot error - 33.6%, Other human error - 3.8%, Weather - 23.1%, Mechanical problems - 19.2%, Sabotage - 20.3%. The highest relative frequency is 33.6% which corresponds to pilot error.

Step2: Determine solution for the threat

To address pilot - error threat, pilots could be better trained.

Answer:

D. Pilot error is the most serious threat to aviation safety. Pilots could be better trained
