Which lighting type results from the glowing of a heated filament?

Explanation:
Incandescent lighting is produced when an electric current passes through a filament, heating it until it glows. The filament, usually tungsten, emits visible light as it reaches high temperatures—a process called incandescence. This glowing filament is the defining feature of incandescent bulbs, which is why this option best matches the description. Indirect lighting describes how light is distributed (reflected off a surface) rather than how it’s produced, so it isn’t tied to a glowing filament. Laminates are surface coverings, not light sources. A horizontal tablet isn’t a lighting type at all.
