Answer:
The answer is D) creation of the motion picture industry.
Explanation:
Edison's laboratory is the birthplace of the Kinetograph (a motion picture camera) and the Kinetoscope (a peep-hole motion picture viewer). Motion pictures became a successful entertainment industry in less than a decade, with single-viewer Kinetoscopes giving way to films projected for mass audiences. Furthermore, Edison's company also also produced films for public consumption.
