The correct option is B Vespucci considered the new continent to be something entirely different from Asia.
Amerigo Vespucci was an Italian explorer who journeyed to the continent of North America around 1501-1502. Unlike Columbus, Vespucci was sure that the continents of present-day North America and South America were entirely separate from that of Asia. In 1507, Martin Waldseemüller, a German cartographer, produced a world map in which he named the continents after Vespucci. "America" is a Latin version of Vespucci's first name.
