Answer» Correct Answer - C Feron `(C CI_(2)F_(2))` is an odourless non- corrosive nontoxic gas which is stable even at high temperatures and pressures It has low b pt low specific heat and can be easily liquefied by applying pressure at room temperature It is therefore widely used in refrigerant (cooling agent) in frigerators and air conditioners .
