Global exploration by sea was made possible primarily by

The correct answer is: D) new technology

When Vasco da Gama, a Portuguese nobleman reached India in 1498 and opened the Asian Route for European countries, it helped Portugal become one of the world biggest powers. Before the establishment of this route, Muslims had the monopoly of trade with India and other Eastern Nations, when Portugal reached there, Portugal became the main seller of those goods in Europe. With this route, Portugal expanded its empire by discovering Brazil by mistake, establishing provinces in India and China.

This was only possible because of new technology such as Caravels which had speed and maneuverability, Galleon which made possible to convert ships into trading and war, Astrolabe a measuring tool, the Magnetic Compass, and Compass Rose and others.
