Cold plasma offers a wide range of useful applications, including the hygienic handling of food, the treatment of various skin conditions, and the filtration of water in underdeveloped areas.

The development of technologies that can operate at room temperature was made possible by fundamental research conducted in space.

Sensitive medical devices can be quickly sterilized at low temperatures using low-temperature plasma treatment.

Temperature required in  cold plasma treatment is 35°C i.e. 35 + 273 = 308K

Hence, the option 303 K-313K is correct.
