Correct Answer: Guglielmo Marconi

Solution : The correct option is Guglielmo Marconi.

Guglielmo Marconi was a trailblazing scientist who, in the 1890s, used radio waves to send signals across several kilometres. Marconi, an Italian inventor and electrical engineer, is credited with being one of the key figures in the development of radio communication technology. In 1895, Marconi successfully transmitted a radio signal spanning 1.5 miles (2.4 kilometres) in Italy. He improved his wireless telegraphy system and achieved even longer-distance transmissions in the following years.
