The correct answer is option B. “The Seven Cities of Gold” is a famous myth of the 16th century which lead the Spaniards to believe that gold and many treasures could be found in the New Spain (now Mexico) territory. The cities were named Halona, Matsaki, Quivira, Kiakima, Cibola, and Kwakina. These stories were of much importantce to spanish conquerors at the time, however, no evidence of such a site has ever been found.
The rumors of the Seven Cities of Gold (located across the desert) may have their roots in a Portuguese legend, one that told about seven cities on the Antillia island, founded by a Catholic expedition in the 8th century.
The spanish conquistador Francisco Vázquez de Coronado, after hearing about the rumors made an expedition to verify the existence of such place and its great riches, only to find that there were no treasures.
