Correct Answer: CFL Lamp
Solution : The correct option is the CFL Lamp
Mercury contamination is caused by compact fluorescent lights (CFLs) . Within the glass tube of a CFL, mercury vapour is used to generate ultraviolet light, which excites the phosphor coating inside the tube to produce visible light. Broken CFLs can emit mercury vapour if not disposed of, contributing to localized indoor pollution.
