Answer:
c. the 15th century
Step-by-step explanation:
Christopher Columbus was an Italian-born navigator and explorer who sailed for the Crown of Castile (Spain) and discovered the New World. Columbus was trying to find a route through the ocean that would enable Europeans to trade with Asia. His first journey took place in 1492, while the last one took place in 1502. 1492 corresponds to the 15th century (1401-1500).
