Answer

B

Explanation

Inhabitants close to very busy airports are likely to experience health hazards. Because maximum acceptable range of sound is 80-90 dB. But in the places like airports this level is always exceeds thus it creates sound pollution and related health hazards like auditory fatigue, deafness etc. Jet planes generally produce sound above 160 dB which is much more than normal level, thus they also produce sound pollution. But as jet aeroplanes are used for some special purposes, they normally do not land in common (very busy) airports ( without emergency). Thus it has no direct relation in causing sound pollution and related hazards in area nearby very busy airports.
