The correct answer is option 2: travelling to China, India and Asia. Marco Polo was a Venetian merchant and explorer who is famous for his extensive travels throughout Asia in the 13th century. He spent many years in China, serving as an advisor to the Mongol emperor Kublai Khan. He also visited India and various countries in Southeast Asia during his voyages. Marco Polo`s detailed accounts of his journeys, written in a book called "The Travels of Marco Polo," introduced Europeans to the wonders of the East and had a significant impact on European exploration and trade. Although Marco Polo did not discover Greenland, round the Cape of Good Hope or discover Canada, his exploration of Asia played a crucial role in expanding European knowledge of the world.
