Hola Amigo!!!
I Hope You Are Doing Good This Evening My Fellow Brainiac!!
The answer to your question is B. Television.
In 1993, John Logie Baird built an airborne television reconnaissance system for French Air Force. The system used intermediate film method by means in which a moving picture of the scenery below the airplane was taken 16m/m film, which was rapidly processed and transmitted to a ground receiving station.
Hope this helps you!!!
Have a terrific Thursday!!
