In a filament type light bulb, most of the electric power consumed appears as option (b) infra-red-rays
Explanation:
When electricity flows through the fiber, it heats up. Depending on the filament temperature, the radiation is emitted from the filament. The filament temperature is very high, usually above 2000 ° C. At that huge temperature of 2000 ° C, wherein 5 percent of the electricity is converted into visible light, and this rest is supplied in the form of heat or infrared radiation.
