Answer:
c) try to find new trade routes to Africa and Asia
Explanation:
Finding new trade routes to Africa and Asia is a good way to gain a competitive advantage over other European, rival states. This in fact what Portugal first, and later Spain, did during the later years of the 1400s.
The motivation was that the Ottoman Empire controlled the Eastern Mediterranean, and this prevented Western European nations from trading with East Asia and the Middle East with ease.
Portugal opted to look for new routes around Africa, and the Indian Ocean, while Spain decided to look for a new route throught the west, which led to the arrival of Columbus in the Americas in 1492.
I'm guessing that they fought against forces, like the people trying to steal land so they could have enough space to live, farm, and hunt.
I also think that the Native American could have traded or given valuable items to the people who were trying to take their land in exchange for the Natives to keep their land.
To the discovery of America, the " New World"
All of the countries were having a battle of who could build the biggest bombs, guns, tanks, weapons, technology, etc. which created tension between rival countries. everyone was afraid of the next country being too powerful. Hope it makes sense :-)
