The right answer is "D. Guglielmo Marconi"

Marconi is considered the pioneer of radio transmission. In 1896, he went to England, after verifying that there was no interest in his experiences in Italy. In 1899, it succeeded in wireless transmission of Morse code through the Channel. Two years later, he got radio signals to New Zealand. From there, he made many basic discoveries in radio technique. In 1909, he received, with Karel Ferdinand Braun, the Nobel Prize in Physics. In 1929, in recognition of his work, he received the title of marquis from the king of Italy.
