A Correct answer
Explanation

Jet engines produce extremely high noise levels that can cause immediate hearing damage and discomfort. The minimum safe distance of 200 feet from behind a jet outlet is the standard safety requirement to protect personnel from acoustic injury and excessive noise exposure during ground operations. The distance is measured from the jet outlet because that's where the noise is most intense and directional.
