Answer 1

The correct option is D Ethyl mercaptan

It is 'ethyl mercaptan' which is responsible for the pungent smell. Ethyl mercaptan is used as an additive to odorless gases like butane, propane, etc. to give foul smell which helps to identify the leakages in the L.P.G cylinders. - Ethyl mercaptan is an organic compound having molecular formula $C_2{H}_{5}SH$
