Explanation:

Fluorinated gases have very low concentration but very long lifetime which increases their global warming potential. They are not sequestrated out, rather they have to be chemically eliminated or only their production can be stopped. Sulphur hexafluoride, the gas with highest GWP is used in electricity transmission equipment and circuit breaks. Hence, answer is C.
