Correct Answer: Magnesium


Solution : The correct option is Magnesium.

The wire in flash bulbs is made of magnesium (Mg). When an electric current passes through the magnesium wire, it rapidly oxidizes, producing an intense burst of light. This combustion reaction is highly exothermic and provides the brief and intense illumination needed for flash photography.
