Correct Answer: Mercury vapour
Solution : The correct option is Mercury vapour.
A small mercury vapour can be found in a standard fluorescent tube. UV light is produced by the Mercury vapour when power is introduced. A Phosphorescent coating within the tube reacts with the UV light, allowing it to glow and emit visible light. This technique is what creates the distinctive glow of fluorescent tubes.
