    D)  none of the above

    Correct Answer: A

    [a] \[{{O}_{3}}\] layer means the Ozone layer. Supersonic jets exhaust produce Nitrous Oxide \[({{N}_{2}}O)\] which is a greenhouse gas with a large global warming potential (GWP). When compared to carbon dioxide \[(C{{O}_{2}}),\]\[{{N}_{2}}O\] has 298 times the ability per molecule of gas to trap heat in the atmosphere.
